I noticed a couple more things.
The DSGunner/Engineer has the new arms, but the helmet may be new too, which I found odd.
The computer console and the computer "block" piece from the command center are awesome. I also noticed a chair lying kind of out of the way there too.
The real gem is that Probot though. The droid has more articulation (apparently the legs were dumbed down for the current version). This makes me all the more wish we had gotten this set and that droid. I love the new one but the added extra joints on the droid really put it over the top, and all the armor for the space pod is just awesome and I really wish we had all this. The probots floated around in space in those pods in games and stuff, doing their proby things in asteroid fields and such. I really wish we had that and all those computer bits and stuff. You can buy custom resin stuff of those consoles and stuff but they're not as nice as those Hasbro ones I noticed (they're neat though, but not quite as detailed as Hasbro's work). The chair is accurate too which is extra cool.
And obviously we'd all love the echo base troopers. I'm shocked a Torryn Far wasn't part of this or an updated Riekean, but I'd take the set as-is just fine. Hell, ditch the engineer. He's meh.
