Are you people even LISTENING to yourselves and your very weak excuses? It is like you are all arguing just for the sake of arguing. Gears of War will NOT come to the PS3, and I'll show why the most common arguments here are terrible:
The "never say never" and "you never know what the future holds" excuse. The ONLY way that the PS3 could get Gears is if Microsoft and Sony decide to start working together, and frankly, that is about as likely as Iran, Iraq, Israel, and Saudi Arabia combining to become a single nation. Hell, I could say that "world peace" is likely using this retarded excuse, but it won't happen. They have no reason to, and they don't even want to. Sony and Microsoft are major competitors, they won't be working together anytime soon, and they damn sure won't be giving away their potential customers by swapping exclusives that they published.
The "well, Sonic is on Nintendo consoles" excuse. People, the point has not only clearly gone over your head, it is now in the upper atmosphere. The Sega/Nintendo and Microsoft/Sony thing are COMPLETELY DIFFERENT. Sega was in the hole. Their consoles weren't selling enough units to keep them afloat, and they were focusing on too many at one time. They decided to leave the console business because they couldn't keep up and were losing tons of money. However, they didn't want to leave the game industry, they knew how lucrative it could be. So they decided to stay in the software market and just make games for other consoles. Now, unless you expect Sega to make games for the ImaginaryCubeStation 2, then they sorta have to make games on consoles like the GameCube or Wii. They didn't chose this because they wanted to. They chose it because they were making less money than a hooker with gonorrhea, syphilis, and herpes in the console market. Towards the end of the Dreamcast they were selling only a few units a month, if that. They couldn't afford to keep making consoles, but they could afford to keep making games and put them on other consoles.
The "well, Unreal Tournament is on the PS3" excuse. Cocking Hell people, UNREAL TOURNAMENT 3 IS NOT PUBLISHED BY MICROSOFT. What part of that is so hard to understand?
Lastly, I assume that the references to the PC version of Gears of War is "proof" that it will come to the PS3. I won't even dignify that excuse with a proper response because it is so stupid. It is like me saying that because a Mario game for the GameCube gets a DS port then that is proof that it will come to the PSP.
Again, no matter how hard you try to twist the very fabric of reality with these weak excuses, it just will not happen.
So, for the last time, Gears of War coming to the PS3 is NOT GOING TO HAPPEN.
