Bollocks
I've noticed something about the two new crates. The Limited Late Summer Crate's description tells us something:
This crate is special
and cannot be opened yet.
It's contents will be limited
and will only come from
this crate.
Some, but not all, of the
items in this crate are
Strange...
And the other one, Director's Cut Reel, has something in its description as well:
This crate contains four
items randomly selected
from a small set. You can
adjust which four items are
selected from your
backpack.
The Director's Cut Reel appears to have a four-digit counter slapped onto it.
