This ultimately doesn't bother me, because once we make the final transition to no discs all digital content, there won't be any reselling of games at all. You don't go trade in games you buy on Steam any more than you can trade in music you buy on iTunes, and that is where we're headed. This is part of that step towards the disc-less future.
There is much more pricing parity on those platforms as well. If the used market is gone, then i hope there will be more and better sales like Steam does...thats not likely because these games will have to support retailers too.
