I think it'd actually be pretty cool if the actual game had multiple DCPU versions in the universe. It would give it even more of 1980's computing feel.
Explore the planet, fight off hordes of zombies to obtain... a DCPU16 - REV C!
It's not certain if there's going to be different DCPUs with different specs. Notch has said[1] that there's definitely going to be versions with different clock rates floating around in space or on abandoned spaceships.

Everything I hear about this game makes me want it more and more.
Notch has said that when he "upgrades" the DCPU spec, the old CPUs will continue to work as they have, but new CPUs will become available. I don't have the reference handy though.
While it might be using an unofficial sprite spec, everything you linked at 0x10co.de is using an unofficial input and graphics spec… That's what the community does: fill in the missing pieces!
0x10co.de is based on official input and graphics specifications taking directly from the DCPU emulators Notch has leaked/released.
I found a bug in minesweeper. Start new game, don't move selection, press F, press F again and enter.
There's plenty of awesome things being done with the official specifications though, like this minesweeper clone: http://0x10co.de/lqnit and this simple raycaster: http://0x10co.de/o3xss
Vim is also in the process of being ported: https://github.com/DanielRapp/0xVim
