This is strange.
Maybe they don't want to announce the delay so close to the Watch_Dogs delay? That's a one-two punch of disappointment for the PS4 launch.
The problem is- the further away they get from Ubi announcing WD's delay, the closer they get to the actual PS4 launch. :/
On the other hand, maybe there really isn't a delay and they just don't want to comment on the rumors?
Sony has been weird about that. On some things you have Yoshida coming right out denying rumors. On others, they are more silent. Remember when many assumed PS4 would have DRM simply because Sony didn't comment on rumors that it would have it post-Adam Orth? "They are not commenting! It must be true!"
Either way, they should confirm or deny this ASAP.
