Don't know yet. Gut would probably say 2009 is going to be the peak year but hey crazier things have happened in recent times haha. I would like to see how Move and Kinect impact the market (although I don't think Move will have too much of an impact). Also curious to see how 3D impacts the market. Not necessarily the one for PS3 but how 3DS does. Although there is somewhat of a separation of handheld and console, if 3DS does become pretty large, it might take some focus away (or even drive video game sales in general like DS did).
But a pricedrop would definitely help but always saturation points for those. But I think 2011, as some are saying, is a potential peak year for it. Sales this year are looking to match that of last year, although not entirely sure until we see this holiday season as PS3 had a big one last year. But I think with 2011, given a lot of game support and potentially a $200 pricetag that it might be able to edge out 2009/2010 (if it is able to go above it).
Another note is to really pay attention to when 8th gen consoles start getting announced. With pricetags coming down, that also means less profit/revenue. So getting a new system out is important and we will probably start seeing announcements in either 2011 or 2012 (at least one next year). That could definitely affect sales, especially if one releases in 2011.
