The most interesting thing for me in this is the article implies that they offer globally distributed consensus. Not sure if this is their actual offering too, but the example of NYC and Signapore implies this. While reads would be fine, the latency for writes could be atleast 2*250ms (roughly the speed between furthest AWS regions). I can still see this useful for applications that require strong consistency and global distribution, but likely a niche. Would be real interesting to see some actual numbers!
