I'm more concerned that I won't have access to the games because I don't play on Xbox or Windows.
It's like the difference between Comcast buying a small, local ISP vs. Comcast buying Verizon in terms of scale and number of people impacted.
I have long term fears that month-to-month game subscriptions will eat the world and in 15 years people pay for games in the same way they currently pay for streaming videos ($10-$20/mo to many content providers).
