Summer Claim Checks??!?!?!

Alrighty, so what the hell are these things people have been asking, well it's pretty obvious ain't it? Your probably going to have to redeem these in order to get the crates, and maybe when you redeem them you'll get something small, maybe similar to crafting Trading Cards, or Halloween items, you know? Just speculation here people, no real hard evidence but in all honesty all their going to do is make our life hell trying to keep the sheet updated with all the damn new items being implemented during the TF2 Summer Update. Hope it gets here soon!
