I don't think so. The team that's now working on 7D2D is not the same team we had a few years back.
Now we have 2 AI guys, several Art guys (modeling, texture and so on...), several Design guys, Madmole can focus mainly on the general picture.
The only real bottlenecks I see are Gazz (who's the only one working on tying everything up in the XML) and (I think) Robert, who's working on RNG.
