Is there any proof aside from this address? Since this is not enough information to look forward and believe Satoshi would return on that year.

He didn't even bother to give a hint on his/her identity how much more his return on industry? For everything surrounded on that address is just another speculation and maybe people are so excited to know what will happen if Satoshi will go back in the scene. Its better respect the creator decision to go away on the scene and let him/enjoy his silence.
