Will MMO Platform Segregation Continue?

Thanks to Stratics Central for hosting an opinion piece discussing whether MMORPG titles will stay segregated by platform, or whether (as in Final Fantasy XI's dual PC/PS2 release) the separate SKUs will "adopt salient features and begin to look alike." The piece points out that in-game controls matter: "In the world of MMOs, the PC is king for two of many reasons: Key binding, and the mouse-keyboard combo", and concludes that "The irony is, for most of the consoles to compete with the PC [in MMO titles] they must become more like the PC."
