Yea, there was an "anonymous" post on Badweb yesterday that said the announcement was incorrect and there'd be no AX reveal at the AIMExpo.
It's gonna be at least a year before I'm ready to buy, so I've really got nothing to complain about. It will be interesting to see what they do bring to AIMExpo; I'd guess we'll at least see the Hero lineup for the US and maybe some minor changes in the RX and SX 2015 models.
