It isn't quite necessary right now. The games that were close to 50GB on PS3 were actually using duplicated data for higher read performance, coming with extras and more languages (Uncharted 3 had 6 languages, if I'm correct), high quality audio, high quality cutscenes and so on. PS4 can deal with compressed data on discs (because of the hardware decompressor), so the games can be compressed saving disc space and it will probably be able to run games on 100GB Blu-rays, while the BD tech can probably evolve to 500GB discs easily.

We can assume the PS4 can read discs with more than 100GB, since it will play 4K Blu-rays and they are bigger than that.
