And your point is what exactly? That Beatles music on iTunes will sell decent number of copies over the next decade? Well, OK - I will go with that.
The point that I am making is that Beatles release on iTunes is NOT a major event in 2010. It would have been a big deal in 2004, in the early days of digital music revolution.. but not now.
In 2010 - "The Beatles coming to iTunes" rumor just fails to generate excitement, sorry to break it to you. Yeah, it will get some press for half a day, and they will sell some copies over time. But "something you will never forget" event? Hardly.
