Revell went to quarterly announcements this year instead of one big trade show reveal that covered the whole year like they used to do. There was more fanfare with those others because we had a full year or more to talk about them. Tower leaked the 4qtr list early before Revell's official announcement. There's a new guy in charge at Revell now (note to self - I still haven't asked his name). They're going to do some things differently now.
Adding to that, Tower Hobbies is owned by Hobbico, which of course owns Revell
I wonder if the kits getting listed before the Q4 announcement a mistake, or did they think that no one would find them?
