If these rumors are true, the resultant game could be the source of many fanboy head-explosions -- and we're not talking headshots. Hiring SOE's developers gives IW a ready-made team that is very familiar with the nuts and bolts of coding MMOs. Add to it the rabid fanbase tied to the Call of Duty franchise, and mix in the fact that Infinity Ward is owned by Activision Blizzard, and you can see where we're going with this. Could a Call of Duty MMO be the super-secret MMOFPS that Blizzard is involved with? Is this why SOE has started working on PlanetSide 2: to compete with a potential MMOFPS hybrid from Infinity Ward, Blizzard, and their own ex-employees? While it's all rumor right now, and thus anyone's guess, it certainly makes for a potentially tasty batch of kool-aid.
[Edited to add] Alan "Brenlo" Crosby, Executive Producer for EverQuest II contacted us to let us know that the rumor about the Lead Developer for EverQuest II going to Infinity Ward is absolutely false. He suggested that the rumor may have instead started since previous SOE Lead Developers Jon L. Davis and Rick Baker are working at Infinity Ward currently. So while it seems that current SOE people are off the table, it certainly doesn't stop the potential of a CoD MMO -- especially with talented ex-SOE employees already in-house over at Infinity Ward.
