I'm surprised that they completely ignored NXT.  Religious debates aside, that seems pretty biased considering the amount of progress NXT has achieved in one year.  The NXT monetary system is about to go live, which will allow for digital currencies to be be issued and traded on the NXT blockchain, and they can even be minted using proof-of-work or backed by locked NXT.  Following that are plans to implement coin-shuffle on monetary system coins.  IMHO these are going to be very interesting projects to watch in 2015.
