Xbox releasing all their games on as many devices as possible has not been a popular move with it's fanbase, but is going to be the route they're going to take in an attempt to maximize exposure and profits to recoup development costs and maximize returns for investors. There doesn't seem anyway of reversing this strategy in the next decade, because of it's long-term goals/results.
Talks also have the next Xbox being a device that will be both a Steam Box and an Xbox that can be as powerful as they want to make it (won't be sold at a loss). Hardware wise they will likely offer up a handheld portable device, an entry level console device, and a high-end console device that will exceed a normal generational console leap.
This being uncharted territory could take many years for this new way of going forward to become accepted.
Now comes the question, Playstation is the market leader in the home-console market between the two, but are they already lagging behind Xbox in moving in the direction that Microsoft is taking the market? Will it be harmful to Playstation by giving Xbox a head-start?
It's likely not a question of when Playstation makes the move to follow Xbox, but when?
