sony have done nothing as of yet, but they have also said (in regards to first part games at least) theres no limits as to what you can do with the physical discs. the thing is what the publishers do and how silly they get with drm and limitations, although a few have already said they dont like what ms are doing as it will limit sales.
as for not thinking its going digital, id say its 50/50, yes they are pushing the digital sales of media so they can do a steam and bag impulse sales, but they will also doing it to control what happens with resales, as well as making sure when there's specials on there not too special as what was asked on that angry joe video where major nelson started to sling the muck at steam when he was asked if ms would do sales as good as steam do. so im guessing they wont be, i know im sound cynical as hell but ms are there to make money and going digital makes them more money per unit, how that will work out units sold i dont know but going off all the polls floating around its going to hurt them id say.
