Yes, those are some of the mechs for the new starterbox and 'game of armored combat' box. There was no mention of new lance packs (or star packs) from anyone I talked to. They are not the absolute final versions, but pretty darn close.
Glad I could get some pictures out there for the folks who aren't able to get to GenCon.
I did NOT get a picture of the marik-painted plasic Thunderbolt mini though. I think they got Dave Fanjoy to paint it at the con, and put it in the case on Saturday. I did see it though, and it was pretty. I still really like IWM's primitive Thud sculpt, but this new plastic one is also a great sculpt.
