Interesting list this year. 2177 and 2826 moved to other events, while 141 appears to be opting out of a chance at the Michigan State Championship to attend, having qualified for the FIRST Championship via Engineering Inspiration.
1806 won an award at every regional it has ever attended except Kansas City last year, and has been either a Finalist or Champion at almost every regional as well. 93 has been around for 14 (!) years with their fair share of cool robots and an event win in 2008. 525 was inches away from a win here last year and won with 93 in 2008. 2062 is pretty much the coolest team around and they've won their share of regionals.
I'll miss 2502 though
