Yes I'm fairly certain that this is something a read about a month ago, from the World DMB site.

As far as I can see it sells DAB+ as a way to cram lots more services into a multiplex, and says sod all about the possibilities for better audio quality. But then what do you expect with Quintin Howard being in chairman (or what ever) of World DMB.

It also suggests that using DAB+ will always require slightly lower bit rates because of the RS coding overhead. In reality however the addition of RS coding will allow broadcasters to reduce FEC encoding from Level 3 to Level 4 which would more than make up for the capacity used by RS coding. Hence this is only really an issue for broadcasters who are already using level 4, which is virtually nobody. I wonder if they deliberately made this part misleading so as not to shoot the old DAB system down any more than they absolutely had to.
