This is a big problem with developers these days, honestly.
They don't work out creative solutions to problems, they just demand more powerful hardware so they can do things easily.
It's really killing a lot of the joy in games.
Kojima illustrated this as a core difference between Japan and the West at a past GDC.
I think it's because western developers always worked on the PC where more powerful hardware was always either already available or coming within months. Japanese guys on the other hand are more inclined to stick with what they've got and design around it.
That's why I have a feeling that the most interesting stuff on the Wii-U will come from Japanese developers. Other than Ubisoft the West might not give a shit about it, which is Nintendo's problem - they want more unique control styles, western developers want more powerful versions of the status quo.
I don't think I've seen a single western developer yet make really good use of motion controls or a touch screen (outside of iOS).
