Previously it was pretty well thought that the upcoming Apple event would be on January 26th.  However, a new report from All Things D are saying they have inside information that an event will take place, but on the 27th of January.

Sources in a position to know tell me Apple (AAPL) is indeed planning a media event later this month at which it will announce a major new product. The gathering is to be held at the Yerba Buena Center for the Arts in San Francisco, a space Apple often uses for media events like these. According to other sources, it will occur on Wednesday Jan. 27, not Tuesday Jan. 26, as had been rumored.

It appears that the date is really up in the air at this point.  Until someone gets the official invite we just won’t know.
