I found the replies on this tweet funny even reading that the tweet makes CW look more legit to be Satoshi.

, and one following that it is a good news LOL. I do not know if the reply is deleted or was buried by the current reply since I can't find them to take a screenshot.
Anyway, it is highly possible that the post is made by another person and not Satoshi, there are lots of refute on the replies and many are sarcastic.
I have a feeling that this may not be Satoshi, but then we shall see in coming weeks or months.
Satoshi can easily prove himself by simply signing a transaction from his wallet and put this whole drama to rest.
Indeed, it would shock the world if that Twitter account signed a Bitcoin message from the address that is known to belong to Satoshi.
