More RAM?Its probably going to have a camera for Facetime as well as some memory and CPU upgrades. But probably not much else.
Dual core CPU?
Improved screen?
Thinner?
Lighter?
Camera?
Video out?
What more does it really need? Seems like a decent upgrade to me, but those with buyers remorse will always try to convince themselves otherwise.
To the OP, wait for iPad 2. Oh, and we don't need stupid, "in that case, wait for iPad 3, then iPad 4" comments either.
