If you will-call it @ ARB you'll surely be getting the Simpson IIIC (my conotation, not theirs) but if your buying from other sources verify which tent your getting and make sure your comfortable with the differences, ie the changes between the SII->SIII->SIIIB and the SIIIC (which isn't even in the states yet). I've heard form more than a few that have bought tents NIB to find out they were an older model and to be fair I'd suspect that most retailers don't know the difference unless they follow the changes. I'd venture to say that any company hanging around ExPo is going to be up to speed on the changes, upgrades and differences.
