Every week you say this, and every week I wonder where this 'psychological barrier' really lies.
The Vita has shown a marked improvement over the last 12 months. Gone are the days when the 3DS outsold it by 20 to 1 (hell, one week was 47:1!). The baseline has risen, support has risen, localisations are rising. The platform is trending in the exact opposite direction to last years expectations.
You always say it's 'selling bad', but you conveniently overlook the fact that everything is 'selling bad'. At least the Vita isn't getting worse with every passing week / month like the other platforms. Sure, it's selling bad, but bad is better than holy-fuck-when-will-they-pull-it-off-the-shelf.
Also, every week I think 'thank fuck it's still over 10k' so you're wrong if you think that fear has gone away.
