The following comments come from Grant Davies, co-founder of developer Endgame Studios...
"We sold the distribution rights for that to N3V Games. Basically, what happened was, toward the end of the project when they were looking to place it with distributors, the DS market kind of fell down at that point -- the 3DS was coming out. They had a bit of trouble placing it with distributors. With the 3DS, we got involved with a publisher on that one [Ignition], and they. Now it's no publisher, and we have the rights, and we have a completed game, so that's why we're kind of thinking maybe eShop is the way forward."
If the game does hit the eShop, expect it to be split into two parts.
