It think it can affect things. Switch can barely handle Xbox One ports as it is. If the Xbox One is going to handle cross gen games about as well as a Switch handles cross gen games (I can't phrase this better), then the Switch is going to get cut off from multiplatform development. This has been happening with Nintendo for the last 10ish years so how will that affects things currently? I really don't know. I don't know how multiplatform titles are performing on the Switch. If the Switch is selling solely on Nintendo games, then it won't affect much. If it's selling on a combination of games, then it will be affected.
