Seeing that I work in retail I knew the Vita's day were numbered. The Vita section of my store (Best Buy) is down to one game, Danganronpa: AE, and no consoles. It's been like that for about 2 months now. Granted Best Buy isn't the largest game retailer but we had the second largest Vita section in town for the longest time. Now Gamestop is still the top having ~20-25 games on hand and now the Walmart I went to a couple days ago had about 10 games which surprised me. Everywhere else, no dice.
It's sad but I've come to terms with the Vita's situation in the US. Honestly the Vita could have easily been discontinued in 2014 (in the US) and most retailers wouldn't have cared. It's a miracle this little handheld has made it this far and is still kicking and to that I salute the Vita!
