Safe bet? Remember Android and Middle Earth Quest?
Firstly, I did say it would depend on sales. Obviously a game that doesn't sell well won't see an expansion.
Secondly, "safe bet" does not equal "guarantee."
MoM seems like a game that could be easily expanded from what I know of it. Unique characters and monsters, modular board peices, etc. And since the Mythos is public domain it's not like FFG needs to worry about licensing fees, which have been an expansion killer in the past.
I don't have any idea how well Android sold, but it doesn't seem to be as big as games like Descent and AH. MEQ probably did sell quite well being connected to a recognizable name brand, but as a licensed product it would cost more to continue building on it than on an IP FFG owned, so maybe it just wasn't feasible.
