Your abit late honda, everybody disregarded that statement 23 posts ago. Maybe you should relax alittle bit.
Anyway, back when Rogue Leader came out Factor 5(Julian) did say that it was possible to run RL even on the PS2, it just needed tweaking. But he didn't go on to the amount or what needed tweaking. Also the RL was based off the N64 version code which allowed for the fast development time but had also produced some porblems like crashing and for time to time inconsitant frame rate.
Now we have Rebel Strike. this game has been written from scratch around the GC hardware. Now with any program it can be ported from system to system with differant results. Factors include time and money, talent, limitations of the recieving/original hardware and so on. It can almost be a straight port like PC to Xbox due to the similiar hardware or near total rewrite say from PS2 to everything else out there. But all this talk is pointless as one, it's IGN, two, Factor 5 don't do ports as in they don't port things themselfs it would be a third party of some sort ala Gearbox for Halo. Three porting 3 games in one year is abit bit of a streach considering Rebel strike would have to be largely rewritten or some nasty shortcuts taken. And lastly, it's IGN.
But this generation has been very wishy-washy. It is almost impossible to foresee anything.
