What you forget, OP, is that the ps3 programming is completely different from ps2 programming.
While your argument works for onimusha, because the programming is nearly identical, it doesn't work in this scenario. They would have had to scrap all the work they had done already.
Besides, after GoW 1, they had the engine right there. All they had to do was add art assets. The games are pretty much identical gameplay-wise.

Lol, some of you are way overreacting...

However, all in all, this makes no sense...

Wow

we are talking about THE same gow as the one which sold 3,2 millions units and 2,5 on ps2 ??? (which is more than 98% of PS3 games?)

the gow which sold 2 millions units on psp ?

Right ?

Its a really good re release, it brings a demo too

^Damn leo you changed your avatar?

Of course they re released it to make money, also to widen the userbase to make GoWIII even bigger.

conspiracy abounds!
