And I believe they've removed it from the latest-gen Pentiums
This is not true. VT-d and ECC were thought to be removed, but these features were simply unlisted, not removed. Intel Ark now shows them as available, e.g: http://ark.intel.com/products/97143/Intel-Pentium-Processor-...
Not much of a surprise coming from AMD, but it will most likely end up like their previous generations of CPU: most motherboards won't support ECC memory, forcing you to buy specialized hardware anyway. And if you're buying specialized hardware, you might as well go all the way.
Who needs a Xeon now? The only chink in the armour here is the 64GB max, which admittedly is bad for the science/Machine learning folks, but the vast majority of these chips is used for databases, web serving, app serving, etc, for which these ECC-enabled Ryzens are a game changer on price. Cluster them up on premises or in cloud, and you're looking at a total winner, especially that the 16GB dimms are still much che…
ECC support in CPU is just a half of success. Now somebody have to convince motherboard manufacturers to enable it. It was the same thing with previous AMD CPUs. They all had ECC support but there was virtually no motherboards that would support it.
Can someone tell me how many errors over the past 10 years or so would have been fixed by ECC memory. I've no idea at all how much better it would be and what the current error rate it prevents is? It sounds more nice to have than vital? Is there a performance cost to it at all?

That's demonstrably not true, AMD has supported ECC more or less across the board since the Athlon64. Enterprises may be professional cost cutters, but before that they're professional ass coverers, otherwise Oracle would have died 20 years ago.
No one got ever fired for buying Intel Even if Ryzen will be twice as fast enterprise will still go with Intel. Unless some company with reasonable size (like DigitalOcean or Linode) will adopt Ryzen in their servers and brag about it.

Exactamently. Even if Ryzen has a way better performance/price ratio than Intel, it's a risk:
* risk of losing favour with Intel or vendors (aka getting "renegotiated contract")
* support risk
* less coherent hardware risk
* software compatibility risk
Ryzen is lot of risk, and the reward is not huge because at the end of the day CPU is a pretty minor investment. Unless Intel completely fucks up a generation as they did with P4 few company will be willing to take that risk. Hell even then most companies remained on the Intel ship.

Would prevent Rowhammer attacks.

Even after the whole kerfuffle about Intel paying off OEMs? [0] They got some pretty huge fines for that.
But in all seriousness, I think that if Ryzen can hit the perf/watt numbers of Intel, companies will seriously look at purchasing AMD systems again.
Back in the NetBurst days, lots of people were buying Opteron servers because they kicked the pants off Intel. If AMD can prove their competitive with Intel again in the data center market, people will buy their chips.
Competition is always good, even for large enterprise, and if the TCO of an AMD Ryzen system becomes on par with Intel, enterprise will happily pit them against each other in a price war. Enterprise will absolutely buy from both.

If you look a the Linux 4.10 change log [1] you will see that while zen supports ECC, it ignores the error correction message. So you can use ECC ram, but you get none of the benefit of ECC ram

will there be any "cheapish"(consumer) dual socket motherboards?
