Welp, it looks like vita has survived for a full year.
Its price point only dropped a bit for holidays, and as of two weeks ago, has outsold the 3ds pre price drop.
It's debateable, but according to the timelines, both did most of their sales outside of holidays at the higher price point. 3DS launching in Feb 2011 and price dropping in august, and vita releasing last couple weeks of xmas only in japan, releasing ww in late February, and matching the sales right on black friday (160k week).
I say it's debateable because there's debateable issues such as "does a launch during last couple weeks of xmas in japan only really count as holiday" and "does 160k on black friday really vount given the increase was minimal".
Either way, what is important is that Sony managed to hold out, and may likely hold out until late summer depending on the numbers this december and sales when the winter lineup is released.
For reference, WW, it took sony 9 months exactly to sell what 3ds did in 5.
Doesn't look all that grim anymore does it?
