Probably not. Considering how poorly Vita is performing, the apparently shrinking HH market and the financial risk of releasing a new HH in this situation makes it seem less that likely. I don't think Sony is willing to throw away money like that right now, or in 2-3 years time either. Nintendo is dominating that market, and even they are losing ground. That's quite telling.

Furthermore, I think VGChartz should add a "Like"-button.
