This years fair started just today and there are some pictures online already.

A very early news list.

Mainly aircraft and afv in various scales. Not much 1/72 so far.
As the listed sites clearly state, both will see heavy updates over the next few days.
So, it could be worth to check them more than once.
Since the fair will continue until Monday, I will collect more announcements before I post a detailed & almost "complete" 1/72 news list here.
