Holy madness.
First off the 20th is the ps4. Don't fret. I and many other people in this forum have talked to folks who are a part of it.
Secondly... I'm not saying it's impossible, but this is the first time i've ever ever ever heard a peep about a 4g vita. Will investigate. But this site certainly isn't a trusted source that i know of. Actually i know about as much about this site as I do the 4g vita.
There are rumors of a hardware revision being considered inside sony. It's to make it cheaper... not more expensive.
Calm down folks.
why do you have to be so reasonable..? lol.. "Phone home"..
