HTC is still running off the "critical mass" that it created back in Warbirds.
That's why the game is essentially the same, but HTC knows the territory well and probably is banking/relying on some factors to keep things moving as they are. While for us, whom it seems that things are dying in a sense, its only the factors and the players who we recognise and are part of our part of the reaction, but are not at the center.
The problem is that as long as these factors keep the "reaction" going, HT never has to listen to us. But that is only a problem to us, and not those who keep it running, you see? Despite some of the great ideas that go around the wishlist forum, very few are ever picked up because of this as well. HTC has a confidence that other developers don't, and while; in a world of devs giving what people want immediately, they don't play that game. This is a good thing.
If you want to start a revolution to stop the momentum, that would be murdering the game that you knew and loved so much. There is nothing anyone can do that can be better in this particular territory, so we just have to sit back and let HTC work at their own pace and just focus on having a good time with whatever we have.
A little bit of faith and space goes a long way.
