Would be cool if they did but don't figure there would be much market for them. Was it Academy I think that did a small line of StarCraft figures about five to ten years ago? They did a handful of Terran marines and the Hyrolisk. Sadly I picked up the Hyrolisk and then couldn't find the marines anywhere.
Smeagol you might try Infinity.
They're 25mm gaming miniatures but much of the powered armour has a very Mass Effect look to it.
