NextLimit has released a "learning edition" of Maxwell. It has no network support and you aren't supposed to use it commercially. Says the max res is "Full HD". No more specifics, but usually that term refers to 1920x1080 (respectable enough). Cost is 95 dollars for a 1 year license, or 195 dollars for a non-expiring one. Might be fun to play around with it a bit.
Also, Ton Roosendaal tweeted this today, someone's been working on a Blender exporter for it: http://sourceforge.net/projects/bmaxwell/
EDIT: Fix formatting since someone installed fancy math plugins into the fora since I wrote this OP.
