I figured this was a better place to post this than the rumor mill; in
this thread there are several posts with semi-reliable information on the expected dates for the regionals which have not yet been "confirmed" and posted on the FIRST website. I thought I'd consolidate them here with the justification so you can make your own judgment for planning purposes. I'll try to keep this post updated as other information becomes available, and I'll remove regionals from the list as they make it onto the FIRST confirmed list.
I copied the regionals from last year's list, removed the Indiana Regionals and added a couple of new ones that have been advertised. Sorry, no District information - I'm not sure what's still missing there. "Blog Post" numbers are the posts from the referenced thread.
