Well, to be fair, sales of the PS4/X1 could grow as well. I certainly think they will if they follow the trajectory of the last gen......which, thus far, they've done. I think as more and more releases ditch the last gen, we'll see more and more gamers sign up for the new. At least for the forseeable future. I mean, this holiday season for example is going to be huge. HUUUUGE.
But, if they merely match last gen sales of PS3/360 (which I still think they will exceed), hey.....they will still have outsold the previous gen thanks to the mad rush for early adoption of the new cycle. I tend to agree with Queso on the market.....people look at overall contraction thanks to the exit of the Wii as a bad thing, and I just don't think that's the case. That contraction happened years ago, and we've been operating within the new normal for some time now.
Having said that, please understand I do DEEPLY respect your opinion, Zhuge
