I'd like to add that it's not a pro that you can give a game to ONLY one friend and that the friend has to be on your friends list for 30 days, that is a complete negative.
I don't think this will affect the gaming culture in the future because MS is the only one doing this. Sony isn't, PC gaming isn't changing any, Nintendo isn't - MS just ruined their own product and gaming will continue as it has been for the last 7 years or so.
I'm glad I have stayed neutral when it comes to consoles (I have a 360/PS3/Wii/Wii U, no bias anywhere) so I don't feel any extra frustration that I might have had I only been a MS customer.
