The iPad desperately needs more ram, more so than the phones. That said, as I'll likely sit this one out, I wouldn't be too fussed if they stuck with 1gb, keeps older hw relevant for longer.
Can't see it though, with iPad sales not being amazing these days (which I put more down to people being happy with their existing iPads, it's a fairly mature product now, rather than a complete lack of/falling levels of interest), Apple need to do something to stimulate sales. RAM isn't something that sells to the mainstream, but the iPad would be a far more viable* work device if it had 2gb.
*Personally, give me a laptop every single time for such activities
