Yep.
To the OP:
A lot of people are giving out false information because they haven't either tried it or don't have a clue. I got the limited MM edition in the post today and the first thing I was blown away with was how much more responsive all the buttons are, especially the shoulder buttons (it's like going from a normal keyboard to a mechanical keyboard) The C stick is pretty crappy though, that should have been like the vita as in a proper analog stick.
Hardware is about twice as powerful (not just a small upgrade), as everything loads about twice as quick. The screens have more contrast and the Super stable 3D wasn't just hyped up by all those reviewers. I mean it's almost creepy, there's a little demo about how it tracks your face/body. Pretty cool and works in complete darkness too! Finally motion controls and proper 3D at the same time!!!
What I'm saying is that it's not just a simple upgrade and considering mine was v9.0 out of the box, now would be the perfect time to get one or else risk losing gateway compatibility.
