I agree with ZigZag on the probable release window (ahem). I would not expect to see the next Windows version until 2015. It is a major undertaking that requires time and money, so even if Windows 8 hasn't been unversally loved, it will be a while before you see it replaced. I don't think Windows 8 is that bad, personally. If you really give it a chance, you might like it more than you do now.
Released is relative. If you mean released to the public my guess would be about 18 months. I dont expect much more to be done in win 8.1 except bug fixes.
Btw anything you can do in win 7 you can do in win 8. You can even bypass the wonderful start screen be enabling boot to desktop so you neednt even see the start menu.
