Applies to all current BR players too but the application is more interesting in games than in movies.
At the current rate, PS3 games will be hitting the 50GB limit 3-4 years from now and requiring these discs.

Hitachi demonstrates playback of Quadruple Layer Blu-ray Disc using "normal drive"
- Demonstration is playing a QL Blu-ray disc, switching layer and showing its signal pattern by an oscilloscope
- Each layer has different frequency signal pattern (L0:3T, L1:4T, L2:5T, L3:6T) to distinguish easily current reading layer from other layers
- Reader is not a special made equipment, it is based on Hitachi's commercial BD drive GBW-H10N with modified firmware and some part of optics
All players can be updated via firmware. It is assumed that the discs themselves can contain the firmware to install to any Blu-ray device, allowing the laser to read all 4 layers. And since Blu-ray has no lag between layer switches, video and audio will be seamless.
