In four days, GoG will be revealing the new publisher they've signed. They've hinted that it's a high-profile one, with a number of games on the official GoG wishlist.
That's the official story. But there's one other aspect that's of particular interest. A GoG user did a bit of poking around the website, and found a number of images that - it would appear - will be appearing at certain stages of the countdown:
Don't those fonts look awfully familiar?
This could be the big one.
Now, I have to underline, as said in the GoG thread: GoG have been known to be deliberately misleading. I'm reluctant to get my hopes up too far. But, well, that's awfully compelling evidence.
