Who knows.... I have seen quite a few folks ask about it.
I was just posting my opinion. We all have them. 
'Course we do, Shuf. The wish list is exactly what it is advertised to be. Wishes can be extravagant or simple. Practical or impractical. We all know that HT's opinion is the final factor and I don't pretend to have more sway than anyone else (or any, at all).
I was excited to see the BB modeled and hoped it might spark some interest in players that like sea action.
Same could be said for the Sherman, hoping to see more ground events like the Battle of the Bulge.
Both came and went.
I think everyone's looking for a gimmick to bring in more players or inflate interest in the existing community. AH3, IMO (and I suspect some others), is still a great game, as is. It has grown, over the years, at, what I consider to be, a rather amazing rate. So much so that some players complain that there hasn't been a new model of plane added since the huge task of upgrading the graphics was completed (a difficult task, at best, with such a small but talented staff). (I was on the other side of the 'what the game needs and what will draw more players is upgraded graphics' argument, btw.)
So, I've gone back to my pre-graphic update dream mode .... but in small bite-sized (manageable) pieces.
2 jets basically give the AH community a window to expand into the Korean War (a venue with little competition, online but, admittedly, appeal to only historical air combat fans). Maybe WT has Sabres and MiGs but it is more of an arcade mix-mash chaotic kid's game (IMO).
In another direction, adding the I-15, the CR.32 and the HE-51 would open a window for expansion into the Spanish Civil War and uber-bipe dogfighting at the cost of three models. Again, the potential interest of both the existing community and potential new players comes into play with both marketing and the eventual possible need of even more models of that theater/era (bombers, tanks, terrain) needed to be added in a timely manner to maintain the interest (something that never blossomed in the WWI arena). That would take more follow-up than the KWA, which already has a lot of pre-existing toys.
Sea warfare in AH3 has never been truly promoted or marketed, nor can it effectively do so without a lot of ship modeling. The game doesn't offer many terrains for the MA that are basically backdrops for ship on ship strategy battles and without featuring another 7 ship models, at least- Yamato BB, Bismark BC, Shinano CV, King George BB, Tone HC, Fubuki DD, British L class DD. That and working torps on the DDs. Now that is a lot of work with a lot of risk.
So, yeah. We all have opinions and we all have dreams. And we all have opinions on other player's opinions and dreams.
Personally, I also would like to see a few more WWII planes modeled ... but AH3's WWII plane set is anything but anorexic and modeling everything that flew and fired at enemy planes (or dropped troops or flew reconnaissance) has become impractical.
In my humble and limited opinion, jets will bring in more players, if done properly (though I'm still drawing the line at ATA missles - guns on, baby). Just test the waters with the 2 most popular KW models. If I win the lotto, I'll pay for this experiment, myself. Hell, I'd sponsor a go-fund-me.
(In a wildly successful and perfect AH world, it would model air, ground and sea combat from 1914-1953 in six, or so, (full) arenas.)
