I'm starting to wonder if PS4 is going to have a sharp rise/fall in numbers - I.e reach saturation point much more quickly than previous generations. Which might mean it is difficult to sustain a long generation compared to last time around. I also wonder about PS3 vs 360 conversion rates. 360 owners seem to be still buying software - more so than PS3. So are there more 360 owners still to convert, and could that affect the PS4:XB1 ratios later on?
