If Namco wasn't too busy being money hatted by Micro$oft then they would have found the solution that would have made their pockets and everybody happy. Released the game in 2008 for PS3 then ported the game for X360 and released it 2009. They would have gotten all those huge sales numbers from PS3 and also gotten the smidge of sales from X360. The fans would have loved them and they would have profited.
The trouble is, Micro$oft is too smart and too rich for the optimal solution to have been reached. Micro$oft probably paid extra just to delay the PS3 version from being released and also to make it so that both versions were equal. Don't you just love Micro$oft? Always fucking around with their competitor's customers.
Giving the 360 the left over shit isn't making everyone happy. Everyone from PS3 to 360 is getting the left over shit (graphically) from the Arcade version plus loads of online/offline modes and customizations and more to make up for it. Microsoft never paid Namco for Tekken 6, that was their decision. Microsoft paid Namco for Tales of Vesperia and that came to bite them in the ass didn't it?
If Namco focused on PS3 then Tekken 6 would be better than the Arcade version, load time and resolution issues would not be there. Just look at Tekken5:DR on PS3, it's way better than the Arcade version.
360 fans don't really care about fighting games anymore because of their lousy d-pad and tekken doesn't have boobs like SC4 nor leggy babes like SF4, that's why were seeing the low numbers. I think 360 fans wouldn't have cared if Tekken came out earlier, it's Micro$oft that's worried that they may lose a significant portion of their install base to PS3 if they allow PS3 to keep their exclusive titles.
If M$ didn't pay for Tekken, why is it that both games were released simultaneously when the PS3 version was ready by 2008? My suspicion is M$ always muscles its way by paying or making some sort of iresistable deal to the company.
