"Hi everyone, we know we have a big community of FPS fans here… so we are very sorry to announce that we will not be releasing March of Heroes. Our developers will be focusing on developing various awesome games in the months to come and working on making them even better. Fans of March of Heroes should definitely look forward to the powerful Modern Combat 3. We are however, not cancelling our work on the Unreal Engine! We are expecting to release these games starting 2012." 
As Gameloft wrote in their statement, they hoped to start using the Unreal Engine in their games starting 2012. The first of these, Wild Blood was released on September 6th 2012.
