The difference being that there wasn't much of an alternative, hence the need for a revival in the first place.
Those who didn't like the Xbox One have settled for the PS4. It would have been a horrible business decision NOT to backtrack on this.
Trouble is I don't think they needed to do a U-turn, if they actually presented the facts at the two presentations. People didnt have a clue about any of the advantages, or why things had to be that way. If they had just laid the facts out in plain English, I think the response would have been very different indeed.
But you can't expect people to piece the facts together from multiple interviews.
