Edit, sorry for the crappy copy, I took the picture on my phone, e-mailed to myself, saved it into a Word file, saved it as an MS paint file, then uploaded it into photobucket..... that's teh only way I know how to do this crap from my work computer, they lock us outta everything!!!!!
Wow, happy for you guys getting it early. I'll be part of the woeful group that has to wait for the original release date unless SCEA decides to play nice (lol). Post some impressions when you get the chance!
The big ticket items are obviously the tools relating to Vita's new interface goodies - touch screen, rear touch, screen-aligned gyro etc. But also a very notable new logic tool in the memoriser.
If LBP/LBP2 were visual creative tools for the dualshock, LBP Vita is a visual creative tool for the touchscreen - alongside all the other nubbins already present in the other games. In terms of giving the game a different character I think that's more significant than saying it makes it sound. All kinds of app-esque and touch-based toys and games in LBP Vita should be possible.
Just called my GameStop where I'm a high priority regular, the ASM read me their internal email and the street date is indeed removed. They have my copy waiting for me when I stop in on my way to work.
