Your predictions are just too unreasonable to even reply back to seriously, cause that has to be a joke right? By 2015, the PlayStation family could easily be close to 300 million or more, cuz by then, the PSP2 will be out, and there will definetly be another PlayStation out. And it doesn't even make any sense. Why not give a number, rather than a benchmark, because you really don't know what's going to happen in the next seven years. We might actually be able to fit two new PSPs in there, with the new PlayStation, and considering that the PS3 and PSP will likely push the PS brand to 250-260 million this year, and up to 300 by the end of 2010, you could be looking at saying the Wii will sell upwards of 400 million consoles by the end of 2015 which just isn't happening.
