I made a guess (because Disney loves synergy), but I was incorrect in that guess. Sorry about that.
Anywho, I wanted to try and speculate why this might not happen till early next year.
I know Randy has definitely been busy with some of the great new Disney music releases we've seen this year (Sherman Brothers Songbook and the 2 Haunted Mansion releases), and he (hopefully) kept doing the restorations of the old material, etc.
One thing that I think has been holding up the iTunes releases these days has been iTunes LP, a new feature of iTunes 9, which I think WDR could really take full advantage of, especially with their catalog releases. If, say, WDR were to release an album in iTunes LP that everyone who knows anything about music (or pop culture) might recognize (I'll be predictable and use the Flashbeagle LP for sake of example), then WDR could really rake in the cash on a catalog release and rush more catalog releases out the door (especially since there's still not that much on iTunes LP), so they're prepping even more catalog releases with iTunes LP (and possibly even a few other older ones could have iTunes LPs for them as well).
Randy, feel free to correct me if I have gotten anything wrong in this (very speculative) post.
