If Sony is smart they will come out and clear the air about DRM before E3. I got a feeling they will do the right thing, rumor yesterday was that they put "blocking used games ps4" on hold because of the reception MS got from fans after the Xbone reveal. Hopefully what GAF and Sony fans did yesterday put them over the edge on the DRM issue.
Maybe they will.
But this massive moment most have hit them by suprise as well.
They might prepare something before, but I wouldn't bet on it.
