There are multiple rumors about ZUR blockchain improvements development and hired developer (developers?), but no facts for now.
They did finish new site about a week before New Year and published a new whitepaper (which includes roadmap): http://zurcoin.org/.
There was a promise of listing it on Cryptopia in Q4 2017, but that is said to be delayed to Jan b/c Cryptopia's Team is on winter holidays.
In my POW prediction, about $1bln cap is full of crap, but that crazy dude from #10 have bought a shitload of coins, and I would expect him to invest even more in development + listing on exchanges + PR, which by the end of Q1 could push the price 5-10 times from current level easily.
