Google Talk to add multi-user chat

A Google volunteer translator, Martin, tips Google Blogoscoped that Google Talk might be launching a multi-user chat in the near future as this phrase needs a translation:

Phrase in English: NAME has joined (...)
Translation Help: System messages when user joined or left a muc conversation

Looking deeply forward to this feature and how Google would integrate it in Google Talk (would it be similar to MSN in anyways? or would it be another revolution?) Hope Google has not yet run out of ideas.

My impression of the new multi-chat feature.
