Does anyone think wave 3 might be episode 7 only, and they might be secretly shipping it already to release just into the new year to catch all the ep 7 hype? It would explain the long silence from a company that has had previews up to a year before some things have been released.
I really hope not, and really doubt it. They probably will include one or two new ships from Ep. VII, but I doubt there will be enough to fill an entire wave (two new capital ships per faction, minimum of 2 new squadrons per faction). On the off hand chance there is, I doubt they'd be able to "secretly ship" it, and have it just waiting in stores for us to all be surprised come mid-December.
Honestly, how would they do the X-Wings and TIEs that would make them different than what we already have, but keep them from drowning out what already exists? This isn't X-Wing, where the minute differences between fighters can be shown off, and the details count. First Order Ties, from all outside appearances, look almost identical (colors swapped) with regular ties. What's to keep people from playing all of their old TIEs as the supposedly better First Order TIEs?
The TIE F/O is pretty easy actually. Give it one more HP and increase its cost by 2 points. Makes it more survivable than an Interceptor and normal fighter but at the same time it is not that much stronger.
The T-70 can change its red die to Black and a blue die to black increase point cost by 3 points.
The question isn't how to make the ships stats different, that's trivial. It's how do you make them look different on the table when they aren't painted.
