Are Blu-ray drives going to have CLV and CAV capable drives?

What capable drivers...?

CLV is constant linear velocity. CAV is constant angular velocity.

I personally don't think it makes any sense to have CAV drives these days.

It was an old Laserdisc thing...

But will the PlayStation 3 drive read discs in CLV or CAV or both?

What is the difference?

CAV discs were spun at a constant rotational speed during playback, with one video frame read per revolution, whereas CLV discs spun progressively slower as the disc was played from inside edge to outside edge. A CAV disc holds up to 30 minutes of content per side, while a CLV disc can hold twice that.

As noted, there are no CAV discs since Laserdisc.

CD, DVD and Blu no doubt are all CLV discs inherently.

Also I am sure that PS3 will be capable of reading all discs it needs to read regardless.

Oh, that's what you mean with CAV and CLV... Ofcourse it's the case explained by phloyd.
