If you head over to Starbucks' website, you'll find a cryptic message claiming that something big — they're calling it "venti" big — is happening tomorrow. They've been implementing a lot of interesting changes at the coffee giant, but there's no news on what their big announcement will be. All I know is that on Tuesday, April 8 at noon ET / 9 a.m. PT, you should head into your local Starbucks to "celebrate something big." Oh and the website says not to be late.

So what do you think it is? What sort of big announcement do you think Starbucks has up its sleeve?

Update: Nothing confirmed, but I've heard of a new Pike's Place Brew and individual drip coffees. I'll keep you posted if I hear anything else.
