If Sony wants to truly support the PlayStation Vita, they'll have to recognize if sales are sliding due to a relatively high and prohibitive price tag.
It will become more obvious that lower sales are due to the cost when we get all that software. A lack of games is always a big reason to avoid a new hardware purchase, but with 25 titles ready to go for launch day and a lot of reported third-party support, software availability shouldn't be an issue.
However, there may be signs that Sony should consider a price cut at some point in the first half of 2012. In fact, it may be bound to happen; one European source is reporting that some Japanese retailers have already discounted the 3G model of the Vita by as much as 20%. Remember, when the Vita comes stateside, the Wi-Fi-only version will cost $250 while the 3G model will run you $300, and that's not counting the cost of the necessary memory card.
The PSP Go fell in price relatively quickly, and the PS3 got a price cut in its first full year on the market as well. The more accessible the cost, the more likely it will be to sell, right? The Vita has proven itself as a highly competent piece of technology, and one gamers ought to really enjoy. But maybe it needs to be cheaper before it can begin to realize its full potential as a next-gen handheld device. We'll have to wait and see.
