I've read a lot, both sides contradicting themselves. We have on the record the 0ne is also up to the publisher.
I haven't seen Sony contradict itself so far, remarkably they seem to have actually learned from past mistakes. They only really came out with information yesterday. Microsoft on the other hand has contradicted itself numerous times and even in its official page on the subject isn't entirely clear. They claim its up to the publisher but also say that you need to check in every 24 hours for example.
Sonys explanation could not be clearer, it is exactly what we have right now with current gen consoles which is why it appeals to people so much. In fact it's slightly better since they are ditching their own online pass system entirely for the PS4. If a publisher wants to pull a SimCity then customers can choose to ignore that game rather than have DRM implemented for every single game they buy.
Anyways I think it will be more interesting to see how and when Microsoft walks some of this stuff back. They have to give somewhere - price, DRM, etc.
