Notch posted on Twitter about the subject of Herobrine, early in his popularity boost.

RavenBurga Is : "he" a real entity ingame or is it just a successful_troll.swf?

Notch : It's not real. =) But it might be soon!

This confirmed there was no Herobrine, but suggested Notch planned to add him at a later date.

At MineCon 2010, Notch confirmed Herobrine will be in the game, probably in a "seecret friday update".

Due to increased drama surrounding the Herobrine page, a wiki administrator asked Notch over IRC if Herobrine would be added:

12:25 Kizzycocoa : is there any confirmation on his upcoming existence in MC?

12:27 Notch : i have no plans of adding herobrine as is, but I do like the rumors, haha

This shows Notch has decided against adding Herobrine. However, the fact that "as is" suggested that something like Herobrine may be added, fuelling beliefs he will be added even further. So, once again, the same user asked for clarification:

Kizzycocoa : the entire community is getting frustrated by the hero-spam

Notch : i have no plans of adding herobrine.[2]
