There's already a "KotOR III: The MMORPG"-rumorthread at KotOR subforums, but to put the content aside, don't try to overanalyze pressreleases people. They are usually written without any substance to fall back to, the only rule is that you should not lie....too much.
But it is not unlikely that some genius back at Lucasarts discovered that their focus-groups complained about the lack of MP and co-op (=pod-people who once thought that Vanilla Ice was edgy and cool) were the sole dissapointments of the series and got the idea of "KotOR + MP = MMO" means double, no wait, tripple amount of sales.
And what are Bioware(EA), who sweared highly and mighty to never touch other IP's again, going to say about it? Not much really.
