Get your cursor off me you damned dirty ape!
Say what you see. If you see it, say it.
From a post on the Pandemic Facebook page ...
The new second edition of On The Brink will be released late June/early July.
We know we had previously announced an earlier date, but we decided to add a fantastic tray that will be able to hold all the components from Pandemic, On The Brink and In The Lab! Every pawn, research station, petri dish, card and more will have its place in this new tray that will be included in all the new edition On The Brink boxes.
So it looks like it will have space for base game and both expansions. Plus they mention petri dishes, so I guess they'll be in there too.
Although it's a shame the release has had to be pushed back another month or two.
