I'm going to disagree there. My sister has Windows 7 Home Premium and all of her XP apps run perfectly. Heck, even all the ones I usually use run perfectly.

That is true, however, notice it is at
very high detail settings. Most gamers on this forum will be fine with just high detail settings. And like everyone knows, Crysis is a very demanding game on the GPU. It takes a real enthusiast to go out and buy a graphics card that can handle Crysis on very high details at a smooth framerate (I consider about 30 to be smooth enough, but people will disagree with me there, so for this, I'll say 60 is the 'smooth' point and say 30 is 'playable').
Of course, look at benchmarks for Dirt 2 - it's a full-fledged DirectX 11 game and even ATI's most budget card at the time I'm writing this post, the 5750, can run it at a playable framerate up to 1920x1200. However, if you're running at that resolution, I think you would opt for more graphics power than a budget/mainstream solution.
That being said, smaller monitors (like 1600 by 1200 or lower) can be driven perfectly fine with a budget card, like the upcoming 5500 series or 5600 series.
Besides, if you look at DirectX 10 games and their benchmarks (like Devil may Cry 4 for example), you can see that even a 4670, a mainstream budget card under 100 USD, can play the game at a playable framerate at 1920 by 1200.
Quote: "dx11 engines will force you to buy at least such class card to play max settings,"
This is true, however, the people who want to play max settings at 60 frames per second will buy an enthusiast card. This is because that
suits their needs. If people are comfortable with 30 or 45, they will buy a more mainstream solution because it
suits their needs. If they don't have a huge monitor and want to play it at 1600 by 1200, they will buy a more budget card, because it
suits their needs.
What I'm saying is, if you really want to have 60+ FPS on maximum settings at a high resolution, you must be willing to spend the money on a high-end card - and that's what enthusiasts will do.

Putting that aside, look at the way TGC programmed the DX9 version of DBPro and look at how they programmed FPS Creator. On the FPSC forums, many people still have 'budget' cards (9400GT or the HD 4350 to name two), yet still have very playable (40+) framerate with source code modifications and plenty of shaders. If TGC actually do decide to make DBPro X11, and if it's anything like DBPro X9, then a budget X11 card would give a very playable framerate, even with higher level shaders. Heck, even people with integrated graphics processors from ATI/nVidia (HD 3200 or GeForce 9100) can run DBPro games at a playable framerate.
If DBPro X11 rolls around, people with DX11 supports (Windows Vista/7 paired with DX11 supported graphics processor, integrated or not) will be able to run it at a playable framerate. And given the development time of such a product, and taking into consideration that the DirectX SDK that contained DX11 was just released in August 2009, by the time TGC would have made it, people will have DirectX 11 support.
