It does look great, but it would be even better with a higher resolution. Better for videos, photos, and more.
Assuming Apple does give the third iPad a so-called "Retina" display, I'd assume that we'll also start to see 1080p videos on iTunes... plus Apple is also rumoured to finally be revealing a third Apple TV STB next month at the same event [much more likely I think than an actual Apple branded TV]... 1080p streaming at last? All goes together...

The rumours all suggest the third iPad will be quad-core... allegedly using the quad-core equivalent of the CPU & GPU in the iPad 2 / iPhone 4S' "Apple A5" SoC, which would give the "Apple A6" SoC a quad-core ARM Cortex-A9 CPU and quad-core PowerVR SGX543MP4 GPU - that's the same as in the PS Vita!
I'd also assume more RAM, plus the cameras definitely need a boost (although personally I don't care about that as I don't see the point in a rear camera on a tablet).
I'll be there day one
[subject to availability]
If the third iPad maintains the same price points as the iPad 2 currently holds, then this time I'll be going for the 64GB WiFi only model... more space for videos & apps, especially if it will be able to handle 1080p videos (my 32GB model is almost full now). If for some utterly stupid reason Apple goes against history and does a price bump this time, then I'll stick with 32GB.
March is going to be great. Mass Effect 3, iPad 3, Game of Thrones, Mad Men
