So I picked up the new core set today (at a regular Target that wasn't open at midnight -- the X-wing set was on a bottom shelf and a bit hidden but there were about 8 there).
Just started unboxing and noticed that there's a new set of asteroids -- different shapes, and including a new large asteroid. Wonder how that will be handled in the tournament update?
Also there's an initiative token (more attractive than the Armada one, with an X-wing on it). The new templates have the S-loop and T-roll on them. Plus there's some revised satellites and a "squadmate" ship (the old Senator's shuttle token) for missions.
The rest looks the same. ID tokens are 1 through 6 and TLs are A through E.
