Blu-ray is justified, says Sony

Will this story be construed as flamebait? Some may think so, but we think it's just a way for Sony to reach out to consumers and say "hey, see, the investment into a new storage medium, Blu-ray, was worthwhile after all!" See, Project Gotham Racing 4's developers came out and said they were not going to include different times of day for their tracks -- not because they couldn't, but because they were unable to fit the texture data onto the DVDs for the game.

Dave Karraker took the opportunity to jump into this announcement with one of his own: "Next generation games simply need more space on the disc to contain all that high-definition content. Take a look at Lair, for example, already pushing 25GB of content, and that is a first-generation title." While it's still hard to really differentiate between the games on the two competing consoles in terms of sheer graphical ability, there is a pretty telling gap between the different options available to a game with a lot more free memory space to fill. What do you guys think? Is Blu-ray a justified investment, or would DVD's have been good enough (would you want to have 3 discs for Lair)?
