Was I?
I largely agree with you. Sony needs to be doing better with the Vita, they've gotten off to a slow start, and this market itself isn't what it once was and is providing them with extra challenges as a result.
But worst case scenario, this thing struggles along for several years being a disappointment before discontinuation. Failure is an option but a disappearance in 2013 simply isn't. That suggestion that it could go away in the next few months is all I ever was contesting and you did state it.
Unless Sony itself implodes, the Sony Vita will still be on store shelfs a year from now with new hardware and games still being produced. It's not at any risk of disappearing anytime soon.
