Why are people getting excited? Everyone knew it was going to happen. We just don't know when. We still don't know when. Nothing to get excited for.
the excitement gives us hope (for me anyway) even if its a false hope and the game is only going to be released in like 6-8 months from now its still gives us the illusion and good feeling that the game is soon to be released so..it makes it feel like the wait is almost over and thats what keeps some of us hyped enough until we really get the PC announcement..you get my point.
