I went through all the rogue abilities I use (or would use if I had a Sub rogue) and compared them to the new abilities to see just how much we're gaining/losing. I don't guarantee this is all accurate, as different pages on WoWhead sometimes had conflicting information!

All rogues lose Burst of Speed, Crimson Tempest, Shroud, a ranged finisher (Deadly Throw), Tricks of the Trade, and Preparation.
Recuperate is gone, and replaced by Crimson Vial which heals 30% of max health over 6 seconds on a 30 second cooldown.
------------------------------------------------------------------------------------------------------------
ASSASSINATION
Assassination rogues now have the monopoly on poison and bleed effects in the rogue world.
They have forgotten: Ambush, Blind, Gouge, Smoke Bomb
They are the only ones to get Shadowstep. Shiv is now a high level PVP talent and puts a debuff on the target causing a 3 second cooldown on any spell or ability they use. Garrote is now usable outside of stealth (though the silence effect is only applied if from stealth), and awards one combo point. Kingsbane is a very large nature damage attack from the artifact weapons.
Hemorrhage is available as a talent to Assassination rogues.
---------------------------------------------------------------------------------------------------------
COMBAT/OUTLAW
Combat rogues suddenly become pirates. *sigh* They also mysteriously have forgotten how to apply ALL poisons to their weapons or to cause their opponents to bleed. Slice and Dice is now a Talent on the same tier as Marked for Death and Death from Above. Killing Spree is also now a talent.
Combat rogues also lose, in addition to all poisons: Cheap Shot, Garrote, Sap (though they keep Blind and that works from stealth), Revealing Strike, Smoke Bomb, and Shiv.
Saber Slash replaces Sinister Strike
Pistol Shot replaces Shuriken Toss/Throw and also has a slowing effect
Run Through replaces Eviscerate
Between the Eyes replaces Kidney Shot and also damages as well as stuns
Riposte kinda replaces Evasion
Blurred Time, an artifact trait, causes cooldowns to recover 200% faster while Adrenaline Rush is active.
Bribe - Bribe a non-player humanoid to fight for you for 5 minutes. (30 minute cooldown)
Track treasure on the mini-map.
Roll the Bones - Finisher with a random combat enhancement effect.
Curse of the Dreadblades - Artifact trait - Cause your Saber Slash to fill your combo points and Lose 5% of your current health when you use a finishing move for the next 12 secs. 1.5 min cooldown.
-----------------------------------------------------------------------------------------------------
SUBTLETY
Subtlety rogues use a lot of shadow damage now.
They have forgotten all poisons and bleeds, along with Hemorrhage, Ambush, Garrote, Slice and Dice, Blind, Gouge.
Gloomblade (a talent) can replace Backstab and do shadow damage.
Shadowstrike is a 25 yard teleport and lots of damage from stealth.
Smoke Bomb is a high level PVP talent.
Premeditation is a talent.
Honor Among Thieves is now a mid-level PVP talent.
Rupture is replaced by Nightblade (DoT)
Fan of Knives is replaced by Shuriken Storm
