Different information has been released compared to 5.1 currently on the PTR (Public Test Realms). First, the patch notes are up to date on the US site here.
This patch will notably bring the conflict between the Horde and the Alliance back to the fore with the start of the pandaren campaign and two new factions (Alliance: Operation: Shieldwall / Horde: Dominance Offensive) which will bring their lots of new daily quests, rewards at stake.
A third faction named Brawler's Guild in Stormwind and Orgrimmar, will offer fighters a chance to test their PvE skills in single-player battles against the most powerful creatures in World of Warcraft.

- Blue item PvP 458 (season 12) + 1500 honor points = Blue item 466
- Epic PvE Item 489 (raid) + 750 Valor Points = Epic Item 493 + 750 Valor Points = Epic Item 497
- Epic PvP Item 483 (Season 12) + 750 Conquest Points = Epic Item 487 + 750 Conquest Points = Epic Item 491
These data are likely to change between now and the launch, as the assembly has not yet been fully tested (source). The principle remains however very interesting and my points of valor, useless for a while, will be able to allow me to improve these few blue pieces that I cannot change!
If you would like to help improve this patch, you can read the FAQ or the PTR forum. And don't hesitate to tell me the results of your tests, I haven't found the time to go there myself yet?
