VGC has PS3 down 29% through week one of April against 2012. (2.17m vs. 3.05m). If PS3 was at 85m I think you could make a case it would likely top 100m, but at the moment, 90m-95m looks more likely, with an outside shot at 100m (80m year end 2013, 8m sold, 86m year end 2014, 6m sold, 90m year end 2015, 4m sold, 92m year end 2016, 2m sold, 93m year end 2017, 1m sold, discontinued).
On pace for 8m in 2013 - assuming it doesn't decline further when Wii U, X720, PS4 all have major releases, and assuming Wii / X360 don't get price cuts.
X360 is down to 1.46m in Jan-week one April 2013, against 2.26m in the same time frame of 2012 - a 35% drop. PS3 in early 2013 is selling essentially what X360 did in early 2012, so that's likely a decent idea on how PS3 will perform next year. X360 is on pace for 6m in 2013 - again assuming the new console launches, and rival console price cuts don't hurt it.
One thing is for sure at least - X360 is the least likely of the three to get to 100m. PS3 is at ~98-99% of the lifetime sales of X360 with weekly sales in 2013 15% higher year to date. I don't think PS3 will get to 100m, but it's maybe a 10-20% shot.
X360 could be at 80m by the end of 2013, 84m by the end of 2014, 86m at the end of 2015, 87m at the end of 2016.
Should end up at something like 102m Wii, 92m PS3, 87m X360, pretty solid growth over the PS2 era machines.
