Interesting? I'm not sure how well it'll play without hotkeys, though... and no mouse. If there's online it might be interesting since reaction times will likely be way down.
It looks like it's out-sourced to "Feral Interactive", so I doubt they've spent much time on it.
I think Halo Wars is the prime example that an RTS without mouse, hotkeys and keyboard does not need to suck. Tho dunno how much you can compare a gamepad with a mobile phone
