With 4K Blu-Ray's coming, it's marketshare will only rise.

how many layer discs will they need for 4k? I'd imagine they'd need 200Gigs. The availability of multi layer blu rays will only be good for consoles. 

It depends on how godo the new h265 is. 4K is roughly 4 times the size of 1080p. So 4 times the video content. Current Blurays are at 50gb but that includes extras, multiple audio tracks etc. all encoded with h264 so yes the logic would be that you'd need 200GB. However h265 is trying to decrease file size through compression by 50% meaning that a video encoded with h265 will be half the size of a video encoded with h264 and look the same. 

So 100GB will probably be the aim for bluray discs, triple layer 33GB but who knows!
