Uldar Easy Mode?

After 1 day of patch day, we are seeing almost all the new bosses being down. Only 2 is left standing but I guess it's just a matter of time before they are beaten. More update on this soon.....

Updates:
Currently Ensidia (EU) and Exodus (US) defeated General Vezax (a few guild has also downed him since) and are trying the final boss Yogg-Saron. This is 1 of 2 boss and the other was Algalon the Observer that was not available in PTR testing and I'm pretty sure it will took more then 1 day (maybe) to get him down.

From what I've read about Yogg-Saron, this is a 2 stage/phase fight. The 1st phase is where you fight about a gazzilion mobs until the named npc (Sara) changes into Yogg-saron.

The 2nd phase is just like C'thun(AQ40), he is protected by a magic barrier only breakable by killing tentacles inside him and you will also have to deal with all the tentacles he spawns in the room.

This part of the fight heavily relies on the Sanity mechanism. Each player starts with 100% sanity and most of the abilities of Yogg-Saron will lower it, when a player reaches 0% sanity he is permanently mind-controlled by Yogg-Saron.

To make the fight easier, there a Keepers (previous defeated bosses in Uldar) that you can get help from that will give your raid buffs according to the keepers that you talk to.

In my opinion you won't be seeing PUG ULDAR anytime soon :(
