I sure hope the next version of the LEX comes together soon, but that will most likely throw more used LEX 1.0's into the used market at a lower price point. The real key is the changes to the strut and wing design...if it all works out, LEX 2.0 might be around the corner.
Supposedly, the tower is going to be a bit lighter, but the new CompTech shock, "tool-less" ratchets, and "pinless" design might make up the weight difference. All are really cool new features for the tower.
As for the T-bar & Wings... we'll have to wait and see what that will be like.
