--- Comment #4 from wanderer@fastmail.fm 2012-04-04 21:29:27 CDT --- It looks like you're probably right; numerous people who have reported their system-profile information are providing similar version numbers (according to e.g. http://us.battle.net/d3/en/forum/topic/3229373318 - and in http://eu.battle.net/d3/en/forum/topic/2592320158?page=11 , at least one of them explicitly lists one such report as being on Windows rather than via Wine).
So this probably isn't a Wine issue per se, though it's still weird.
Oddly, though, one profile reported in that first linked thread reports a version of "Windows 8.1.1.3214 (Service Pack 3)", which wouldn't make sense with that explanation either. Still, since it's highly unlikely that was run under Wine, I don't expect you to waste your time trying to figure it out.
Closing as invalid. If it turns out that this *is* a Wine issue for some reason, this can be reopened.
