I think Sony's decision to include blu-ray was largely due to them wanting to continue the strategy/tradition they've used in the past, by introducing a new larger format to replace the old with each new console - It worked well for them in the past. People shovel the trojan horse idea around way too much I think, and I really believe it wasn't their main motivating factor here.
I don't think that anyone can argue that CD format was a major advantage when the PS1 entered the industry against Nintendo64. And DVD may have had a larger role than most of us realize in keeping PS2 games from going multi-platform to the cheaper gamecube last generation. (for example gamecube didn't get a GTA game)
