Summer of Arcade on the Xbox dashboard states that those who purchase all five games in the promotion will receive "Crimson Alliance and all three characters as a gift." The line is oddly specific, separating the game from the characters, so we followed up with Certain Affinity.
"When Crimson Alliance launches, the full game -- all the content and characters -- will be priced at 1200 points," the rep told Joystiq. "We've discussed other pricing options with Microsoft that gives players more flexibility. We expect that to be finalized and a formal announcement closer to launch."
Crimson Alliance was a standout XBLA title at E3, where the developers alluded that the game might not follow the standard pricing model. With the "full game" costing 1200 MSP ($15), which is the standard price for most original XBLA titles now, it'll be interesting to see what alternatives are provided to those not seeking full membership in Crimson Alliance.
