Random epics.

[Hetrofi]

The epic raid loots in cata classified as random seems to be a mystery to me.
I know that random normally means "of the sorceror", "of the monkey" or "of stamina".

Is this the way its gonna wrk in Cata? cause if it is, most of them will lack stamina, and will be incredibly hard to get the right one.

does anyone have detailed information on this?

They'll have random secondary stats, similar (but not identical) to the suffix system for greens. However, it's very likely that they'll be limited to at least semi-useful stats for the classes/specs they're intended for. The itemization team created these random epics in an effort to get more people to use reforging on them.

e.g., you won't get cloth pants with +expertise or +dodge, but rather +crit, +spirit, +hit, etc. The stats they get will be useful, but maybe not optimal - you're intended to reforge them into something better suited for you. The primary stats (stamina, strength, agility, intellect) are likely to be fixed or tailored directly.

They'll probably use the new suffixes, which I'm pretty sure all have stamina.
