Supplies! Well, no... not really. It was only a matter of time, and now, that time is now. Or, at least it will be come June 28th.
That's when a Crystal White PlayStation Vita will be released in Japan. And while it's not yet announced for North America, I'd say it's a safe bet that Sony will make that announcement at E3 during their press conference.
"But Anthony, what about limited edition bundles featuring anime girls?!?!", you ask? Sony has that too. On August 30th, a Limited Edition Hatsune Miku Project Diva Crystal White PS Vita will launch, adorned with an image of Hatsune Miku on the back touch panel—right where your grubby little fingers are in position to rub all over her.
See them both in action in this handy-dandy trailer below.
