Correct, good to see you took to the time to see pass the hype and research it. ADSL2+ is coming alongside 21cn, wether or not they are classing this as part of 21cn or just doing it at the same time for marketing reasons I dont know. But on the whole it looks like 21cn is something to reduce their costs and they have decided to market it as some magic upgrade, most people might be fooled into thinking the speed increases from adsl2+ are as a result of 21cn when it will have nothing to do with it.
As Stuart said as well for the people who dont have short lines the advantages will be very small if any, adsl2+ most of the speed benefits are lost on longer lines.
In addition things like this are worrying.

Quality: Voice quality on 21CN will be the equivalent or better than PSTN as
the use of Multi Protocol Label Switching (MPLS) prioritisation technology will ensure voice calls are given precedence over less time critical communications such as email. By employing state-of-the art technology, helping to define appropriate industry standards and through rigorous assessment of voice quality, BT is seeking to ensure that voice quality on 21CN is optimised. The bottom line is that no-one should notice any difference.

So 21cn will have qos and is needed since voice will go over VOIP backhaul, is this going to be a 1st stage in wholesale level traffic shaping and premium fees for unshaped traffic? only time will tell.
