Other then a new wing design and being re-engined, whats new about it? Sure it uses the existing jigs at the plant and has commonality with the 777 and 787.

Did I miss anything?

I think I remember reading it is longer allowing more seating.

Major changes are stretch (ca 30 pax more), new 787 type engines, wingtips similar to 787 (wing won't be redesigned), and new flightdeck, similar to 777 to increase commonality.
Additionaly there will be changes to increase interior flexibility and increase in range.

Official company rhetoric:

"The 747-8 will use the technologies of the 787 Dreamliner to significantly increase the passenger and freighter capabilities of the 747 and offer greater fuel efficiency, improved operating economics, and be more friendly to the environment with reduced noise and emissions."
Both versions of the new 747 will feature GE's 787-technology GEnx engines, meet Stage 4 and QC2 noise requirements, have reduced emissions, offer lower trip costs and have an upgraded flight deck and an improved wing.

The 747-8 Intercontinental passenger airplane will be stretched 3.6 m (11.7 ft) compared to the 747-400 to accommodate 34 additional seats in a typical three-class configuration. The only jetliner in the 400- to 500-seat category, it will have a range of 14,815 km (8,000 nmi) and will feature the new Boeing Signature Interior.

The Intercontinental will be quieter, produce fewer emissions, and achieve better fuel economy than any competing jetliner. It will offer 21 percent more lower-hold revenue cargo volume than the 747-400 and cost about 8 percent less per seat mile to operate. Compared to the A380, it will offer 22 percent lower trip costs.

The 747-8 Freighter will be 5.6 m (18.3 ft) longer than the 747-400 freighter. With a total payload capacity of 140 metric tonnes (154 tons), including tare weight, the 747-8F provides 16 percent more cargo revenue volume than the -400. The additional 117m³ (4,124 ft³) from the longer fuselage offers space for four additional main-deck pallets, two additional lower-hold pallets and two additional lower-hold containers. Cargo can be loaded and unloaded on the 747-8F using both the nose and side doors for maximum speed and efficiency.

Compared to the A380, the 747-8F will offer 20 percent lower trip costs. In addition, the 747-8F will maintain the operational flexibility of today's 747 freighters, with good profit potential at less-than-full loads.
 
The 747-8 Freighter complements the existing 747-400 freighter family, which is the air-cargo industry's standard. Both models accommodate 3.1-meter (10-foot) high pallets, providing operators with maximum flexibility.
The 747-8 also fits easily in today's aviation infrastructure, flying into more than 210 airports worldwide without additional, expensive infrastructure changes required.

The 747 freighter family currently constitutes more than half of the world's total freighter capacity. Boeing freighters of all models comprise more than 90 percent of the total worldwide freighter lift.
Boeing forecasts the need for about 900 airplanes -- passengers and freighters -- in the 400-plus-seat segment over the next 20 years. Boeing also forecasts that large widebody freighters (65 metric tons and above in capacity) will comprise 34 percent of the freighter market by 2024.

I haven't so much cared about the weeny bit of details,  it was new information to me that the cockpit will be remade similar to 777.
I wonder how many airlines are willing to buy the new 747.

Current 747's are used less and less in the passenger traffic, although thats probably due to cost efficiency of the newer planes.
For passenger traffic the 777 cockpit remake might be a good choice, because (I think) then they could use 777 pilots to fly the new 747 and the newer, more efficient engines could make it a choice for certain routes.
Could be a choice for the airlines operating 777's, thats probably the main idea.

though.. about half (or most? at least most of the newer 747's are cargo versions) of the current 747's are used as cargo planes, but 777 isn't used as a cargo plane.
That would require the current cargo 747 pilots to be retrained for the new cockpit, which of course isn't cheap.
There could be less interest in the cargo version of the new 747.

Hopefully there will become competition also in the general aviation, those planes are getting kinda old with the design.. Cessna making new designs based on the old cessna... yay.. boring.

In regards to the Cessna, they're actually working on what they call a 'Cirrus killer' design.  O-540, composite high wing plane, will probably cruise in the 160-230k range.  I'm guessing it'll look a lot like a Cardinal.

Of course, my love remains the Columbia 400...  Hail Columbia!
