I realised that the Warbringer shorts (well, the two of three that are released so far) and the Old Soldier cinematics weren't posted on here, and that people who aren't playing the pre-patch stuff might have missed out on them entirely, so I'm chucking them up in the hopes it gets people pumped for the expansion!
I'd say spoilers, but if you aren't playing before Monday 3pm PDT you're going to miss the content in-game anyway.
Highly recommended viewing. :0)
Edit: I've also included the Horde cinematic for the conclusion to the Battle for Lordaeron.
