not really. there are no 32 bit CPUs for consumers anymore (unless you're a sucker). which means there's zero reason to be stuck on win 32bit. (unless you made a bad choice). supporting people with horribly out of date hardware is more costly than just saying "it's 2016, 64bit is what we're doing". though, that says nothing about multi-core or multi-threading or Dx version, etc etc. which are more important factors. just that it's unreasonable to assume the game would be 32bit only.
