Cool Stuff uses multiple distributors, so they'll probably be able to get the game. You could always ask if they plan to stock the game though. Cool Stuff is pretty responsive, normally well under 24 hours for a response.
I called CSI and they weren't sure that they would order it, while Warpath responded to my email stating neither MM or CSI had ordered it and that I should contact them and ask them to place an order. The Warpath rep also said if that was a problem he could point me to some other sellers.
Luckily in the interim, I discovered http://boardgameguy.com/ which has really competitive prices and has assured me they would have Mob Ties in sometime next week. I actually kind of like the idea of supporting them since they aren't the big name OGS but are offering competitive prices.
