Looking initially at the figures it seems you haven't factored in enough decline ethomaz as Superchunk showed although I think he low balled it. I'd say it's looking likely to be around 5 million up from his prediction but I'll try and put some figures together at some point rather than just bash yours.

Possibly. If it cannibalizes PS4 sales.

Wii won this generation. Sales will continue to decline heading into next year, and Sony will be lucky to get to 85 million.

I think 90 million is perhaps a reachable number

ps3 started with a very high price
if I had started with the current price wiiu not know where it could have come

It won't reach 115mil shipped. Odds are next year it'll ship around 9-10mil, then 6mil, then 4mil, and then only a few more after this. 93-96mil is the most likely outcome. People think it will be like the PS2 when it really won't have that sort of selling power; come next year it will be all about WiiU, 720 and PS4.

Im waiting to see if wonderbook explodes with the casual crowd. Its very appealing to children, here in Australia the ads are amazing for it, just depends if Sony can get the word out.

Should scrape a 100 million in 4 years or so.

Seems a bit to much, I think 100m is what it will get to. Im quite sure It will beat the 360 once the gen has come to a close.

perhaps he hopes for china to go wild about ps3 like others did? :D

Lucky? it would be very unlucky if it didn't make past 85 million, and you can't win a generation until all consoles of that gen have stopped selling. We didn't just stop tracking the wii once the WiiU came out.
