Doom 4

Hi Guys,
it's about that time that Doom rocks all gaming platforms again! After the significant success of Doom3 it is now the right time to simply get an official announcement by the owner, which is id Software btw, that they are already working or will working on Doom4 or probably not? Does somebody know anything about it? Any update is much appreciated!
Thx much guys and later!
