Wednesday is going to be rough, as I'm going to try to keep away from the news until they post their keynote video in the late afternoon or early evening, as they usually do.
This worked for me for the iPhone 4s announcement back in October. The MacRumors site even had a convenient page set up to notify when the keynote video was posted on Apple's site, spoiler free and with a direct link to the video. Please do that again next week, MacRumors! I seem to recall that solution being just perfect.
