Thoughts on Xbox games with gold and the future of the program

Recently Sony announced PS Vita and older PS games will no longer be included in their program similar to Xbox only offering two games a month instead of 4. With that do you think eventually Xbox game studios will do the same or do you think they will
continue to offer the 4 games a month service or even entirely new balance of games? I want to know all your thoughts as we entering the age of digital content on all platforms.
