Your sig proves that you make bad predictions. Every prediction is pretty much false or almost impossible to happen.
Wii Fit never will outsell all GTAs combined they will release all the time new GTAs Wii Fit would have to sell massive amounts to catch up to GTA. To Catch GTA there needs to be 50 Million more sales.
Wii wont be anywhere near 80 Mio until years end to reach that it needs to sell 4 Million each week beginning now. Its almost impossible that WII wil outsell PS2 until 12/31/2010. Wii would have to sell every Week in 2010 1.3 Million Consoles thats impossible. Oh wait the Entire Playstaton Family until December 2015. Ok thats 135 Mio PS2 105 Mio PS1 26 Mio PS3 50 Mio PSP around 315 MIO WIIs LTD ? To reach that in 5 years or 260 weeks - around 60-65 Mio Wiis Wii would have to sell for the next five years every week 1 Mio Consoles.
Now you say PS3 will never reach 60 Mio despite the fact that every thing indicates the opposite. Sorry but compared to the 20 Mio GT5s your predictions are atleast 100times more insane. Your predictions are the most craziest predictions I ever heard in my entire life.
to reach 60 Mio until 12/31/2012 PS3 needs 10 Mio sales so even if nothing would change despite pricecuts more games more features it will reach 60 Mio 100%. And there is a chance for GT5 to reach in the next couple of years 20 Mio your predictions are completly impossible to come true.
GT5 has one of the best legs in the videogame world. GT5 prologue sold 6 times better then Gt4 prologue. GT3 was released on a much smaller userbase and still it managed to sell arond 15 Mio. GT4 is the second iteration of GT on the PS and it sells even today and probably will reach 11 Mio the next year(s).
The racing Market had always a lot of games but GT is special it has something no other racing game has. It will sell continously it wont be an explosion like MW2 was but if no other GT will be released on the PS3 then its possible not probable but possible that GT5 will reach 20 Mio. I guess it will sell in the range of GT4. 10-12 Mio. Fact is that the GT Brand seems to be stronger then while GT4 was released the the massive sales difference between the both Prologues indicate this. The attach ratio of 75% is just flawed logic nobody said it will sell it at once thats not the way GT sells.
I dont believe that it will sell 20 Mio but you act like there is no chance in hell that this numbers could be reached despite you are making extremly crazy predictions in your sig. Thats pretty similar to the way like you behaved as I made my prediction why the PS3 will reach 5 Mio before the Wii reaches 10.
I know the PS3 will beat the WII this year in Japan but I am atleast 100times more sure that PS3 will reach 60 Mio until 12/31/2012.
