Competition, as in two, is good enough. The lesser consoles available on the market , the better it is for consumers to get all the games. For me last gen it was a bit of a pain owning all 3 consoles. 2 would be perfect. The way I look at it, we could do w/o one that's the most similar to another. M$ & Sony seem to be clones, so pick the one that's most consumer friendly (Sony) and its a wrap.
Nothing personal at all for me, just concerned about convenience & $$$.
