All Ryzen support ECC, it's up to the MB manufacturer to implement support though, and few have.
It's unlikely that Ryzen Pro will overclock much if any better, their (well, Global Foundries' since AMD doesn't own the plants any more) current fabrication process is designed mostly for mobile type chips with low frequency and low power draw, they just plain and fundamental hit a voltage wall around 4GHz- which is why the far quicker stock 1800X only gets about 200MHz better total average overclock than a 1700 despite starting with a 700Mhz advantage. The Pros may well have better thermals getting up to that point, but won't get much higher. That has to wait for a new fabrication process...
Ryzen2 on the other hand should be on that new fab process and may well allow Kaby Lake style base and overclock frequencies. If they can get a decent IPC boost as well it should be a massive improvement overall.
