Your word has been marked, let's see how you and the other doubters are faring so far.
All albums in the iTunes top 50 allready (highest are number 8, 12, 14, 15 (the $149 box set), 16 so far). And 27 singles in the top 200. That's just in the first few hours of release, and most of the world probably hasn't even heard they are available yet. We'll see how high they go, but so far I wouldn't be surprised if they end up being the fastest selling artist on iTunes. The only other time I've seen this many songs and albums on the charts was after Michael Jackson passed away.
Keep an eye on those charts and see where they go in the next few days. And I'm sure Apple will be sure to send out a press release before long to make it perfectly clear how well they're selling.
Seriously, it's just common sense. When you have a band that has been one of the top sellers for decades, what kind of logic makes you think that when a new format comes along, they're not going to sell well in it?
