Sony recently released an updated version of the PSP which has accelerated sales. They could certainly do it again in the future as sales slow down. They are also tying in better ways to view media on the device which can add sales in the future. Who knows if they will even have to release a totally new portable console that replaces the PSP entirely. If they don't, the lifetime sales could certainly hit 60 million...but I do think the console stocks have been drifting upward uncontrollably.
