At this point I feel like the community is trying to play a Wha Happun episode for EW's content (nothing against Matt and his show, I love it) but without doing any of the actual research or proof for it.

So far what little we know about the FFXVI dev team isnt enough evidence this is being the case besides Yoshida taking the helm for two projects simultaneously, and even then we still have no clue how specifically that entails for the two teams.
