Dont know, possibly, coz they got the console market thats making them lots of money, so there not wasting time and money making DirectX10 games, and they know loads of propor gamers proberbly will pay out like £800 or whatever stupid amount the Directx 10 graphics cards will be to play all the latest games.
Infact, apparently the full Potential of DirectX9 hasent been unleashed, personly, i think its pathetic there releasing DirectX10 possibly this year!, especialy when people are paying £500-£600 for 7900GTX's and X1900XT's and XTX's, directX10 seems to just fix a couple of problems, going to make graphics cards change alot, and fix some of the limitations with DirectX9, but still, They should of waited another 7 months or so.
Apparently, Vista will ship with DirectX 9.0L, and DirectX10.0.
but apparently its like this :'(
To playrectX 10 games, you going to need a DirectX 10 graphics card, and DirectX 10 cards wont play directX 9.0 games very well :s
But the thing is, it seems Microsoft is going to MAKE you buy VISTA to play Directx10 games, coz Apparently, DirectX10 is not coming out for Windows xp, oh, and if it did, it seems like DirectX10 games, with a directX10 graphics card in windows xp, would run DirectX10 games slow, wtf!?!?!
It, seems Game Developers might be making fallback versions of DirectX10 games that are DirectX9.0.
i was reading about the above on the forum, but it seems very wierd, and it seems like DirectX10 is NOT backwards compatible like the other versions of DirectX :\
I dont know if its true, maybe someone else haves some info about it, but it seems like buying a DirectX9 card is just a plain waste of money if your a gamer, it also seems like DirectX10 graphics cards are going to be different, somthing about Common shaders, Geometry Shader :s
and on a hardware website, its also seems that we need to shell out on more money for big upgrades.

DirectX10 & The Future OF gaming.
So what does all this mean for us? The potential for it all sounds great on paper. Since DirectX 10 is tied to Windows Vista, this means if you want to experience DirectX 10-powered 3D games you are going to need Windows Vista, a DirectX 10 video card, and a DirectX 10 game at the least. Windows XP users need not apply for DirectX 10. That said, given the advances with DirectX 9 gaming in the last year, we fully expect to see more of its potential realized as well for those of us “left behind.”
Given the expensive and extensible upgrade path that will have to be traveled in order to support DirectX 10 gaming, we think there are going to have to be some tremendous gaming experiences for sale to get those beyond the early adopters to facilitate a move to DirectX 10 and the needed hardware. The transition to DirectX 10 is going to be interesting to say the least; and we are certainly curious about how it is going to be accepted by the gaming crowd. Windows XP can easily be seen as the best operating system Microsoft has ever produced and we think that PR promises of a usable 3D desktop is not going to be enough to motivate people to leave the XP operating system behind. Much like Ageia’s PhysX, Windows Vista needs that elusive “killer app.”

If they do make a Verion of DirectX10 games for DirectX9, then the DirectX9 verison will look crap compared to the DirectX10 version rite? and run slow as hell on DirectX9 cards rite?
It's just like Playstation 1 and 2, Playstation 2 Games Came out on the Playstation 1 at first, i dont know if they still do, proberbly not, but of course the Playstation 1 version looked crap compared to the Playstation 2 version.
I can see DirectX10 Killing PC gaming, and increasing the Console market, as everyone will want to move to consoles as there cheaper, and with consoles like the playstation 3 will proberbly get graphics as good as the DirectX10 games.
