I'd say that this thread is a little premature. Very little is known about it other than its pedigree, its exclusivity and some concept art. There's little talk of gameplay (apparently it uses the pointer to paint, but we don't even know if it's 2D or 3D yet), and no release date named yet.
Given the powerful IP, and assuming quality production values, it should be able to clear a million sales handily, but I'm not going to try any more specific predictions at this point. My predictions suck enough as it is when there's lots of information out.
