At this point no one knows what the access will be for the early release. They have yet to say that the sports titles will be full access and not a timed trial. It may very well not be a timed trial, and for those who will be taking advantage of this, I hope that is indeed the case.
As I said in a different post, for
me the only reason I would purchase this is for the early access to games, that's it. And based on what I know, even though I don't own the Xbox One, I wouldn't take advantage of this offer. Not for me.
And yes I realize that gaming isn't charity and that it costs money. I'm well aware...LOL.
