Around when will directx 10 games become popular that nearly every gamer has to have a Dx10 video card?

Is it worth to buy a directx10 video card now or wait untill directx 10 games become more popular?|||Microsoft will make their FSX directx 10 patch available in november - another directx 10 game "Crysis" is not due to be released 'till Q3 -2007 - My guess would be not untill later this year if you want to be able to enjoy the latest titles. Probably wont be until mid next year where one could say that "everyone" should have it. - The only directx 10 compatible card right now is the 8800 GTX|||wait until directx 10 cards drop into the sub-100$ range.
