Right now, I'm not really sure what Gato Games is doing. I don't think they're working on any projects right now. However, SuperMechs probably won't get any updates, judging that SuperMechs isn't even listed as a topic anywhere on the Gato Games forums: Gato Games Community - The Gato Games community for BattleDawn, Earth Arena and future projects.
Oh, apparently this exists also: GATO | Join the indie gaming revolution
Wonder if any trademark/copyright stuff will happen.
