I think RM will be more successful than it has been in the past now that there's someone else at the wheel. The first and second incarnations of ICE had the buck stopping at the same person and, as much as there were a myriad of issues facing the company, there was one major problem that ensured RM would slowly decline in commercial viability both times. I won't bother getting into what exactly that was, but suffice to say I don't see it happening again with the third incarnation of "ICE" (i.e. Guild Comp Pub).
There will likely be some hurdles in traditional marketing when you have a print on demand product, but at least someone will be actually thinking about marketing in the first place. For example, a booth at GenCon is actually fairly reasonable. For a couple thousand dollars you could pick up a 10'x15' footprint in the merchant room. As far as manning the booth there are a select few people that could be counted on to actually show up and man the booth (if they commit to go) so long as there was something provided to stock it. Showing up to GenCon is going to get you some minor publicity right off the bat. The same people volunteering to man the booth could also potentially run an event, hopefully something at least attempting to reach for the clamor that Run Out The Guns caused.
