My guess is they changed the date of release. New date just wasn't added into the list before someone went home for the holidays.
Either way, I dont dislike WotC or anythink, but boy do they lack adequate PR & communications. Wether they pulled product without explanation, or due to some oversight just give the (wrong) impression, it's not very conductive to, you know, gaining/keeping goodwill and trust in the company & it's product.
Eh... I think right now no matter what they do, someone will find a way to turn it negative- so I can kind of see why they say nothing.
People harp on every word, and spend all day everyday looking for the most negative way to read it possible then broadcast that message far and wide everywhere they can find on the interwebs. There's just no way they have the manpower to keep up with that kind of insanity, so after a while truthiness takes over...
If they say nothing, there's nothing to spin, and everything people say is at least just conjecture.
I disagree. They could easily come out and say "We have not ceased production of these products. They are just being delayed." I don't think people would have such a hard time accepting that over not hearing anything.
I think people have reason to complain. They told us over and over that Essentials is not 4.5 and that they will continue to support the whole game and so far all we have gotten is Essentials based content. Removing those products enforces the idea that Essentials is the only way they are supporting DnD. Stepping forward and talking about this issue would make me at least feel better about WotC's future.

What it appears they may have decided is to no longer engage a small portion of their customer base through the official forums. Time will tell if that's true or not. Personally, it's hard to blame them at this point. There are always people on both sides any issue, but it cirtainly feels like the "can do no right" crowd have invested in one heck of a PA system. It's hard to hear anything else at times.
