2 disc, even 3 disc (Wall-E) special edition blu-rays are absolutely nessecary.
If a studio wants to put loseless (dolby truehd or dts-hd ma) or uncompressed lpcm audio on a movie, that takes up a lot of space. then you need the 1080p video, with a jacked up bitrate, so the HD content doesn't have compression artifacts on a large HDTV or projector. this all takes up a ton of space.
blu-ray is aimed at high end home theaters, especially right now. the studios aren't going to compromise audio and video quality (lowering bitrate or not using loseless or umcompressed audio codecs) by squeezing everything on one disc.
