Plus, in canon, once he returned to his former power, he was able to break everyone out of Azkaban.
I would be rather surprised if, after all the characterization and buildup we've been given so far, MoR!Voldemort turned out to be capable of this as well.
It might not be a great idea to sacrifice the element of surprise by doing so, but still, if he already had a route to power even greater than he possessed before, I don't see why he'd stall on using it.
As a suggestion: he may have decided that his goals are better served by remaining in his current guise (which he presumably could not do if he regained his body) than by sheer magical power, at least for now.
(The HPMOR discussion thread after this one is here.)
The previous thread is over the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread. This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it. The latest chapter as of 09/09/2011 is Ch. 77.
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: one, two, three, four, five, six, seven, eight. The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.
As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
