GC said a rogue revamp will happen if the warlock one ends up increasing lock popularity.
now let's look at an INDICATOR of popularity. this is by no means popularity itself, but it will give us an idea of how the warlock revamp affected the class.
the indicator I'll use is the class forums activity right here, right now:
Death Knight Forums - 104 users viewing it right now
Druid Forums - 75 users viewing it right now
Hunter Forums - 61 users viewing it right now
Mage Forums - 113 users viewing it right now
Monk Forums - 100 users viewing it right now
Paladin Forums - 68 users viewing it right now
Priest Forums - 71 users viewing it right now
Rogue Forums - 52 users viewing it right now - Lowest
Shaman - 62 users viewing it right now
Warlock - 134 users viewing it right now - Highest
Warrior - 81 users viewing it right now
By looking at this Indicator, it seems the warlock revamp was very beneficial to the class, and so, rogues are next
(also: if you really want a rogue revamp, I suggest you roll a warlock )
