I hope DAB+ will revive it. It has a better codec and much more error correction than old DAB. I like the idea of digital audio being broadcast with a non-proprietary codec and in its own band.
DAB+ uses the same codec as HD Radio which is AAC+. However Ibiquity licenses it under HD Radio codec to make it easier. DAB+ will be a failure just like DAB, and it is completely incompatible with with any DAB receivers.
Many countries that had DAB and shut it down, are actually testing HD Radio.
Spectrum is at the premium nowadays, and can be used for other and better things beside duplicating what is already on the air on FM and AM.
The only country that has any DAB that actually people use is UK, and even there it sucks. Many stations are in mono, even if they are stereo on FM, and many stations are at 80Kbps Mpeg1 audio that is the worst audio codec ever developed.
In Canada they will probably be switching to HD Radio at least for FM. There is already station that broadcasts it. Also many people that live close to US border are buying HD Radio tuners to listen stations from US.
