Well, it really depends on many things.First if XCX finds critical and commercial success(in the west), its possible that Nintendo gives more resorces to them, and also more staff, and they may prioritize their games in opose of helping other projects.It also depends on the next game, if its going to be a new entry in XC or if its going to be a new IP.If its a new XC, then theyy could probably use assets from XCX and ideas pre-estabilished in them, making the development much faster.If its a new Ip on the other hand....
Well, in any case, I dont think they will take an extra 4 years to release a new game.They are already working for 8 months in a new game after all.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
