There's also a Hatsune Miku one, if you're willing to spend near 1k for it:
I don't really want it, but I'm putting a pic here for show. It's limited edition, and Amazon had only one new one left last time I checked. Oh yeah, I almost forgot to say that it's a Japan import.
[EDIT: It's pretty much just the white one, but with Miku on the rear touch.]
I personally have the white one, but only because the AC3L bundle seemed like the best one. It was either AC3L, or Madden or Declassified. Also, the bundle was exactly the same price as the normal system. It's really nice so far, and has almost no visible finperprints (there are a couple faint ones, and they can be easily removed).
Uhh... the Miku vita is $600 w/ shipping at nin-nin (which is were I got mine) but they suddenly made the website french! but the price is still in yen... huzzah. My guess is french warehouse. But $30~40 in shipping on $600 is not as much as playasias $975 pricetag. PA overprices limited-ed consoles....and then everyone follows suit (except nin-nin) but honestly IMO white looks so much better,
As for the side by side its kinda a bad picture so: AC3 Vs. 3G/Wifi.
