If you are a Beatles fan you have their music on (much better quality than mp3/aac) CDs. You have probably also ripped the songs to mp3/aac at a higher bit rate than iTunes will sell you (or maybe to a lossless format). Given that, I would expect some second day stories about how much better the CDs are anyway.

The only reason I would see a Beatles announcement as worth much is if it signaled that iTunes was going to sell music at above CD quality. At that point I could see some really big time sales.
