From the picture on the main page, it is safe to assume that it's the A model that we'll be getting. Honestly, other than extending the runways to so the B-29 could take off (Currently, runways aren't long enough) there really isn't anything that needs to be done for the sake of game play that would require the B-29 to be nerfed in anyway.
It's going to take a long time for the B-29 to climb to high altitudes, and they will be extremely vulnerable at this stage. They're going to be a tricky nut to crack but I look at it as a challenge. I can honestly say that I have turned completely around about the B-29 since I did a little more in-depth research into both the A and B models. Other than a hefty perk price and maybe only allowing single ships instead of formations, I don't see any negatives to the B-29 being added.
If we had gotten the B model instead, well, then maybe my views wouldn't have changed that readily.

The one thing that I overlooked, and I am a bit concerned about (and yes I voted for the B-29), is that IF the plane is perked...this may result in the unintended consequence of bomber pilots running noe milk runs in normal un-perked bombers to pad bomber perks...
I hope this is not the case...

Edit: Logical and potential common sense restrictions for the B-29:
1) Restrict them to rear bases, along the lines of the 163...except more than just one base...make it time expensive to fly them to discourage potential abuse
2) Perk them at a reasonable level (less than the 234)
3) Possible reduction in present bomb perk points awarded for other bombers to discourage milk running
There are ways to manage this and make a ton of fun for the pro bomber guys, while kneecapping the gamers who abuse level bombers...
