There were images a while back of an updated Space Trooper, did I completely miss this guy or has he yet to come out?

I thought that was a mistake. The picture they used was of the Dark Trooper when they meant to say the Spacetrooper was going to be a reissue. I could be wrong.

There was a new spacetrooper that came out in the Toysrus exclusive Solo twins wave. I think there was another one after that that looked more like a regular trooper and had a removable helmet.

I have him. He's basically a Stormtrooper that comes with a detachable backpack and a pipe that plugs into the backpack and tucks under the helmet, presumably an air pipe. Great little figure.
