WiiU is hacked but I don't think its been distributed due to lack of interest.
X1 will get hacked out of spite pretty quickly.
PS4 will depend on what they announce next week. It took PS3 so long due to lack of interest by that community. Once interested kicked in, it was rather quickly achieved.
However, X1 has so much DRM and online connectivity... I am not sure how effective it will be. Likely a way to let it remain 100% offline for retail games and connect to an entirely different network or something.
