The new addressing scheme is interesting. Calling it "new cryptography" is a bit of hype, as it falls out pretty obviously from the original white paper.
It has advantages and disadvantages, and whether it is a clear improvement over payment IDs to be adopted in all use cases is unclear (they are claiming that payment IDs will be deprecated but I'm not sure that is a good idea), but certainly a legitimate development to define and implement it as they have done.
The rest of it -- things like supporting high transaction rates when there is effectively zero actual usage of BCN and very little usage of any cryptocurrency right now -- is pure hype for pumping purposes.
