Next step is a similar experiment lasting several months, so we should get an answer to one of your questions before too long. If it keeps a pig alive for that long then that seems like a good sign. They do say patients would still need EPO injections, since the device doesn't contain the type of cells required for that. And with sufficient funding they're still 4-5 years away from clinical trials, so they seem to agree there's a lot of work to go.
