No changes anywhere makes sense mostly. Standard is too new, even though I'm much higher on the idea of FotD eating a ban in the near future after seeing it this weekend. I think Modern has the shadow of a Mox Opal ban looming over it, but it hasn't quite become oppressive enough just yet. The Jeskai Ascendancy version of Paradoxical Outcome Urza might be the thing that does it, but who knows really? I don't know what's going on in Legacy or Vintage, besides the fact that whatever mono-brown deck will eventually become singleton-plus-4x-Mishra's Workshops as more potentially breakable artifacts and artifacts-matter cards get printed. I don't have a finger on the pulse of Pauper or anything, but not banning Arcum's Astrolabe (and Ephemerate?) seems like the one big miss today based on all the talk I've seen. It takes away so much of the cost for going multicolored in a format where the mana is supposed to be not great.
We'll see if Standard can adapt to FotD decks, but with aggro looking nearly dead in the format and not much that deals with lands, it seems like the outlook is poor. On the Arena Decklists podcast last week Bryan and Gerry got into this a little bit, but with the advent of Arena, people are able to solve Standard much quicker than ever before. They speculated that Wizards should maybe move up the PT's and MC's as a result of this, so that they aren't showing a "solved" format. Maybe Wizards ought to look at both doing that and also doing a B&R a week afterwards in the event that it's needed to ensure the health of Standard.
