If sales are an issue, then it really could go either way.
Halo and Assassin's Creed novels (as well as Magic the Gathering and D&D books) are available in abundance around here, despite being a niche market, but the Dragon Age novels and The Infernal City aren't available at all. I had to import my copy from the United States.
So, either it won't be sold at all, or it'll be everywhere.
I'm also anticipating a similar problem with the Fallout: New Vegas "All Roads" comic. I have a feeling it's
only available in the collector's edition of the game, but if it's for sale in comic shops, you can bet it won't be in any of my local ones.
