All he's saying is that eventually there will be BF4. However, unlike other companies it will be when they can further the technology again as every main BF series has pushed the tech forward.
Usually theres a main BF game like BF2 as an example and then a couple years later some alternate version of similar tech like BF2142 was. Then years after that we get a whole new experience... i.e. BF3. Now it this situation we had filler BF:BC games that were simply testing console technology as well as destruction and the build up of their architecture.
So, I'd expect the same here. Difference is they now have the established Bad Company line. So we'll probably see a BC3 game in 2013 based off of the tech we have in BF3 with some relative improvements related to the new consoles and simply optimizations continued on DICEs engine.
Then in 2014 or so we'll see BF4 with the finalization of these refinements and a full PC-like experience on the new consoles as it will be optimized code specific to each due to them being in the market for 1-2yrs now.
