The DSi is like $170 and the PSP Go is $250. Way too early for a next gen. The mainstream gamer isn't going to pay more than that for handhelds. Throughout history, if there is one thing we learned, it's that expensive handhelds just don't do well in the western market. In Japan, where they are starting to use the things as an outright replacement for home consoles (given low home console sales numbers), maybe it's a different story over there.
