While we're talking guns, I'd certainly like to see a MilSpec weapons TA (in fact, I assumed one was planned, from the way TA 1 feels).
As for specifics, the opening story in T20 is very cool. I want stats for the ETC ACR that the main character is using (unless all ACR's are assumed to be ETC...)!
One other thing- are there any plans to fix the tables in TA1? They look...well, they look really bad and are hard to read. If I was going to actually print out that TA at some place nice, like Kinko's, I'd want a new version with real tables for the T20 weapons. I understand that if this was going to happen, it's probably not very high priority, but it would be a nice thing to do!
