Is there a progressive Timeline?

Haven’t been able to find a timeline but I am curious is there a rough estimate for the Vanilla time line , or a general idea how long until TBC.

Just trying to get an idea of how long I get to enjoy Vanilla and relatively how long I wait until my favorite expansion TBC.
