Yeah we will see on the 21st, but I'm not sure how prodding people to buy two different boxes will go down. It could work out for people who just want games (most people on this site), and everyone else.
Just a reply to your comment on that latest 720 rumour article.
I had heard something about two models being available. I didn't really piece together that it might be something like I suggested. If the 720 version (if it exists etc) doesn't need always online and can play used games. It will be the only thing the salvage my opinion of it.
