I ran across a link to Airmech on JBR's blog. Hadn't seen it before but I gave it a couple test plays and it's pretty dang cool. It's by the team that did Herzog Zweii which was an incredibly awesome turn based strategy game that was available on the sega genesis and turbo graphix.
The coolest feature IMO is the veritech like avatar that represents a hero unit for the controller, so you get plenty of transforming robot action. Its also a lot faster paced than most RTS games that I've played. Has some great sound effects as well.
