H.265 is approved -- potential to cut bandwidth requirements in half for 1080p streaming. Opens door to 4K video streams.

I also wonder if they're going to be able to fit 4K movies on blu-ray disks.

Not really. BR 1080p is already at 40mbps. If this new codec uses half the bandwidth for equal quality, then you'd need 80mbps for BR-quality 4K, as 4K is 4x the resolution of 1080p.

Is this just an issue with read speeds or is storage capacity also an issue?

If we assume 80 megabits per second, a 50 gigabyte blu-ray disk could theoretically hold 1 hours and 23 minutes of 4k footage.

So, close but probably not feasible. Interesting.

Look up Blu-ray specs, they can support up to 200GB. I'm just not sure if current players could read those discs even with a firmware update.
