It's possible that Sony's share be 10% or even something more, but 20-30% is very unlikely. Samsung, Philips, Panasonic, Mitsubishi, Sony, LG, Pioneer and Hitachi are, or were when they created association and standard, all big in optical drives, while TDK is the biggest of the whole association in optical discs, Oracle provided the Java dialect for the interactive contents, Intel, Dolby and the others added some other things. But even just counting the biggest members in the sole optical tech and imagining other techs account for, say, no more than 10%, it's quite difficult to stretch Sony's share up to 20% or beyond.
But let's accept 20%, that means something less than $2 per unit from MS to Sony, not $2-3.
Anyhow, like I already wrote, I still think that if we sum the money on HW and installed SW and FW royalties, plus the royalties on discs, plus the value of MS endorsing and helping spreading the standard (relative value further increased by the fact that during the format war MS was instead fighting AGAINST BD), the benefit for Sony is far bigger than those hundreds million $.
