Crit DoTs for Affliction, sorta

The Shadow Priest world was recently pleased to learn that Mind Flay is going to be enhanced in an upcoming beta build with the ability to crit (as well as a 30% increased spell power coefficient). The Affliction Warlock community, meanwhile, just wanted to know if they'd get a similar treatment, and it looks like the answer is: maybe? Kind of?

Let me explain. Last night, class designer Koraa said the following in the beta forums:

There will be a new talent in Affliction in an upcoming build. Keywords: "DoT" and "Crit" (Well, sorta)

How do we interpret that "well, sorta"? Who knows, really. I'm sure we'll all see soon enough. In the mean time, it's always fun to speculate! What's like critting, but isn't actually a crit? Well, there could be a chance of 1.5x/2x damage, without actually being counted as a crit. This way it wouldn't trigger effects that trigger from crits. However, it would then not solve the issue of crit rating being next to meaningless for Aff locks. "Sorta" could also mean that crit mechanics will apply to DoTs, but not in a traditional way:

A crit DoT could have each tick do extra damage (this would be the closest analogue of a regular crit, I think).

It could be extended in duration, which would save on mana but not really raise DPS.

Each tick could have a separate chance to crit.

It could actually compress the DoT, making it do the same amount of damage in less time, which would raise DPS and keep DPM constant.
