All in all it's a pretty solid hardware refresh (the thinner case being the highlight.) The screen probably will be in v3, since the cost is probably still too high.
Doesn't seem unreasonable coming from the company that claims to have popularized USB:
The next iPad, rumored for September of this year, is more likely to include major new features, including a higher-resolution display and more connectivity (i.e. Thunderbolt).
(Though it's entirely possible it's in the new A5 and they said nothing about it)
Both of these are, I believe, explicit attempts to make people NOT think a new iPad3 is coming soon (so people won't wait, and will buy now instead), but in reality these two things perhaps support the iPad3 in September rumors...
