Jcl has in fact admitted very often that he has no clue when A7/A8 will be out. And back at A6.31 there was a very, very long period without any updates (more then a year).
I'm no fan of this update cycle either, but it's not the first time that we face it.

The real hassle in game development is not the production of the game itself. The main hassle is to make a game stable enough for distribution (polished, bulletproof, localizable, compatible to a lot of resolutions, etc, etc...). I find Unity and Gamestudio are quite comparable at this point.
