People love to overreact. I mean people declared the Wii dead as soon as it's name was announced. Calling a console dead is silly anyway. Even the Dreamcast wasn't dead until it had completely stopped being sold. The Vita just has a slow birth lol
However I still stand by my point and have yet to see anyone refute it. With the current situation and unless there are some big titles announced for this year, then I can see the entire year for the Vita being incredibly tough in Japan. Like I said so far we know of almost no big titles confirmed for this year and it is very unlikely Sony could afford a price drop. It needs one of those two to perform well this year.
When it eventually gets a price drop or big titles then of course it will start selling. The question is simply when will those things happen? As it is they aren't in the near future.
