Next wow patch?

[Shaye87]

Hi guys,
Do you have any idea when is the new patch goes live? Reason why I am asking is because I understand you will be able to create a DK on every realm that you want, even if you don't have a level 55 char on that specific realm. (Still requires a level 55 char on account though).
Thanks!

Also, for example: if i have a level 55+ horde char on server X, will i be able to create an alliance DK on server Y? or it has to be on same side, even if it's a different server?
