I've actually been looking forward to the moment when all our games go completely online so we don't have to deal with retailers ripping us off with used game trade-ins and resell prices.
Developers and publishers make no money off used game sales currently, and Microsoft's apparent new system for dealing with used games seems like a good step. They'll take control away from retailers and be able to set realistic prices. Maybe even set up an awesome online rental service for games so we don't have to pay full price to play! (I'd use that so much, I'd almost never buy a full game again)
If Sony decides to please the hardcore fans who are fighting for used games and no DRM, it'll only hurt Sony (as well as developers and publishers) in the long term for this short term appeasement.
Sure you'll win the right to play your games on those consoles indefinitely, but honestly, how frequently do you boot up your old consoles to play old games anyway? I think the positives of always online far outweigh the advantages of being able to trade games with friends. Besides, wait until we hear their actual plans for used games before making too many assumptions about how evil Microsoft and Sony are. Everything's going to work out fine and it'll be better for gamers overall.
