I don't think that Xbox One will lose first party support this gen. Microsoft had only few studios so that they had to stop working on 360 games to make XBO games (and the wrong people were there to make decisions) but they invested a lot in new studios or bigger studios the last years which should be enough to support a console properly even after some years, not to forget that they finally have someone as head of Xbox who really understands how important exclusive games are.
They don't have a handheld so that the studios they have now should be fine as long as they will release good games and not only many games.
And gratz to your PS4, I hope in some years you will own all consoles which is obviously the best way to go.
