Yeah, the reasons have been listed. Not sure how big the new Vita model will be with Pokemon launching in the same week, though. But it should still boost weekly sales above 10k anyway.
Still, I get what people are saying with regards to the price cut, but with all the new games which have been released as of late, and with it being cheaper than before, having weekly sales so low is a worrying sign.
Which is a shame. The Vita is a real great bit of kit with a handful of good games, and I for one love my Vita. But a lot of decisions with regards to releases as of late. If possible, they should have launched these titles and hardware revisions in either the summer or the winter. Launching them around Monster Hunter and Pokemon on your competitor was never going to set the system alight.
Though, maybe it's too early to say. I hope it does well over the next couple months, but I fear the weight of 3DS releases will crush it.
