Next Xbox - No Disc Drive?

[NICKtendo DS]

This came to mind:
Kinect
No backwards compatibility

When did that need a disc drive?
Granted, the games on disc wouldn't do much, but it'd be the same as every other game on the console.

That,
and peripherals aren't entirely known for being continued into another generation.
It wouldn't be any different from an eye toy or zapper.

I really see it more of a SEGA CD/32X kind of thing, which didn't make it into the following generation, I must admit.
But the lack of backwards compatibility alarms me when we're talking about the 21st century. I always thought of it as a bonus: You have the console, but no games. Luckily, you have previous gen games you can use. If you didn't have a previous gen console of the same series, there may be 1 or 2 games from said gen that you might want to play on the next gen console. Guess I can't play them, so why bother buy them?
Even if they have an online market for downloadable versions of the games, I have little hope for every single game being available.

What was compatible with the Gamecube is almost always compatible with the first released model of the Wii (GBP being one of the few exceptions), and the Wii-U will be backwards compatible aswell (correct me if I'm wrong).

Speaking of which, while Nintendo intends to revolutionize the market by adding more ways to play games, what's so special about not having a disc drive? It sounds like a home-console version of a PSP-Go to me, really.
