Combined they are for sure, it depends what you'd class as A and B tier studios. If you reserve A tier for only the very best in the business then kitler is right (although I wouldn't put Obsidian in that A tier either).i mean they are no Rockstar or Naughty dog. But they are at least as good as killzone era GG and infamous era Sucker Punch. The south park games and fallout new las vegas were great games.
With an upper management that stays the fudge out of their way I think they are fully capable of having their next game elevated to a horizon or GoT level. That's a thing I wouldn't say about double fine for instance. Honestly I think MS mostly wants smaller more frequent releases or GaaS anyways and they won't let too many of their studios really go for the big AAA games. Obsidian might actually be allowed to go big and that's part of why i think they'll have the best games on xbox.
