Topic: According to this, the Wii U's disks will be 25GB in size

That's equal to a single layer blu-ray disk. Makes you wonder if they are indeed putting a blu-ray disk drive in and are just denying it right now. Nintendo is good at keeping secrets. It's great to hear, if true. I'd love to see a Zelda game take up 25GB of space . http://kotaku.com/5809701/wii-u-discs-will-be-25gb-in-size

If Nintendo is just too cheap to pay the licensing or whatever for us the play DVDs and Blu-rays on it, I wish they would have a downloadable app we could buy that would give us that right.

We've come a long way from the 1.46GB GameCube days

@TheBigK : There are rules against digging up old threads without valid cause (this one is nearly a decade old!).

To add a wee bit to the topic at hand though, it's quite likely that Nintendo have also opted for a proprietary format (at least partly based on Blu-ray specifications) as it has a higher read speed than Blu-rays, hence why games can be played directly from the disc without any need for installation. The same is also likely of GameCube and Wii discs.
