I am curious if anything would come from this.
Originally, I was thinking PG would just take what they learned and apply it to a new game - Drakengard 4 would be a good one.
Instead of a bad musou with dragon mechanics, as an action rpg with a more structured approach.
But I guess that's not happening.
Perhaps they should've used some ideas for other games, probably were (for Granblue and AC), but that's not the full SB concept.
I still think this rumor has a few holes in it. I dont' think MS and Nintendo are that friendly to fork over a game with 4 years of development. If development clash led to the game being in a rough state, can PG even fix it?
Really do think, the best case would be that - if PG is confident enough in the concept - that they pitch it to Nintendo/whoever as a from the ground up project using what they learned but not what they had.
