It's live. Seems to be a pegged asset. Do I miss something?
I hope you sold the news... -11% on peercoin
That's exactly what just I did.. and just in time because it keeps dropping.
Doubled my investment of $4 from a few weeks ago. That was of course before I knew about BitSharesX. I'm smarter now. 
Again, referring to the press kit link I included above, the Nu system has very heavy reliance on voting. The way they reduce NuBits supply is clever, but my guess is it won't hold up to high volatility. This is a huge departure from the BitSharesX system. NuBits supply is reduced by paying variable interest on "parked" NuBits; if a NuBit is parked, then it is effectively removed from supply, but it accrues interest. This interest is set by a literal human vote, and there is some strange system of time periods in which votes are taken. And they called BitSharesX "Fed 2.0"...
The interest rate can be increased only by 1% per period, but decreased all the way to 0% in a single period. This strikes me as a bit hacky. One thing it means is that if NuBits ever require a huge supply contraction, the network will not be able to make it happen.
It does indeed sound hacky. On top of that, without an ecosystem (i.e. a corresponding DAC) like BTSX, it seems like a pegged asset is of limited utility.
I don't know... I'm more of the opinion that a pegged asset is really the holy grail. I'm not sure what BTSX does that NuShares doesn't. I mean in a high-level community sort of way. To the spending public, if it has stable purchasing power, it's all it needs to be.
It's now clear that NuBits is the first true competitor to BitUSD. The race will be decided by these three factors, in no particular order
1. Community
2. Interest paid on the asset
3. Price Stability
For point #1, NuBits has all of Peercoin behind it; but I think the BitShares community believes in a better story than Peercoin.
For point #2, BitUSD yield comes from a fundamentally different source (trading revenue) than NuBits interest (central bank-style interest rate incentive).
For point #3, time will tell.
