It'll never happen. The COD formula sells too well. EA will just have two series that tries to compete with COD.
Don't spoil my dreams, you!
EA is setting themselves up for an annual release calendar to compete with the annual pattern Activision has established, but I don't know if they entirely need to subscribe to a true CoD approach for multiple franchises - they risk too much by diluting the Battlefield brand. I think BF3, for the faults it has, it a great compromise and they need to go no further in compromise with the true "Battlefield" franchise. Another Bad Company or another off-shoot? Go for it - but BF2143, BF4, whatever comes next in the proper Battlefield franchise... it should be no "worse" than BF3, and I think EA will be cautious with the property. There's always a healthy respect for established properties and what consumers expect from said property. They'll dance around that line, I'm sure, but I imagine they'll mainly "CoD'ize" the game only through more CQ-like maps, maybe a few more Damavand's and other corridor-style maps with a few vehicles at most.
I have a feeling, if MoH actually does well this Fall, they'll move that into an annual release property - maybe, or maybe not, changing up dev's from year to year. If that's the case, BF properties might fall out of the Fall release lineup, so as to steal attention from any CoD DLC buyers and get them to switch to a Spring-release BF game and ditch the previous Fall's CoD release.
Curious how they'll manage multiple properties, instead of focusing on a single "brand" with an annual release cycle.
MoH this Fall, perhaps BF4 (Frostbyte 2/2.5?) or "BF2143" or BFBC3 one year later, another MoH the year after that, another BF-brand game the year after that...
Hard to tell, and sales are truly going to dictate it in the end.
