My problem (In theory) with no overview is that with a year run, at some point during the AP, they will be going For Pay, I think. (AFAIK they didn't announce yet when, but they've established a price, so it's gotta be on the way.)
Considering that apparently, there are only "Dragon & Dungeon" and "Full DDI" packages planned so far, I think the group of people buying into this only for the adventure path will not be that big. Of course, it still might exist and deserves to be heard. But maybe WotC is taking into account that they can't catch everyone, and ultimiately have to go with the business model that works best for them?
And ultimiately, you do not have to start the adventure path now. You could wait 6 months, a year, to wait for feedback. "Still sucks", "Wow, I didn't expect that. Best Dungeon Adventure Path since Age of Worms!" "Take care with adventure 7, the penultimate encounter is not only harder then the one against the BBEG, it's also very deadly if the PCs don't take the encounter serious", "Too much combat"... There will, even with all the caveats, still be enough playing the path from the beginning. Only those that have doubts have to wait.
And since they are all digital, it is a lot easier to get the adventure paths. (Interesting question: How do they handle this with the subscription? Do I get access to stuff that existed before the subscription? Imagine, one month of DDI to get _all_ Dungeons and Dragons? I suppose it won't be that easy...)
