I would hope so, I don't think there's really anything stopping Intel technology-wise from bringing out CULV Core i3/i5/i7. I'm guessing the reason why they wouldn't is more for market reasons. It's cheaper to make culv C2D's and AMD doesn't even have an answer for those, so why would Intel push the next gen?
Sad (from an enthusiast standpoint), but that's what they do (better for Intel's short-term bottom line, thus stockholders). If there's no market to compete against, they are very lazy/slow to bring better technology around. Reason why there's virtually no improvements on the new Atom. No competition.
