Very adorable. How about Sackboy/girl as an unlockable skin in Second Son? I also agree with the sentiment that LBP Hub should come to PS4 if Sony want it to be relevant. Seems an odd decision to release it right at the end of the PS3's lifecycle.
That being said, I hope the next mainline LBP is a significant departure from the others, as, having played LBP, LBP 2 and LBP Vita I'm not really interested in another that's very similar again.
