Why not get a regular 360 which you can take anywhere and play your discs? You will still be hooking up two devices. I don't think many people will pay $99 to have an add-on make the Nextbox BC with old discs. The urge to play old games eventually wears off, BC is very overrated, and again, why buy a butchered 360 that won't be able to play the discs by itself (so you can't take it to a different room/place, for example) instead of just a regular 360.

I might be interested in that at $99. Then I could move my own Xbox into the kids entertainment room and just hook the mini-me 360 into the Nextbox.

I can see WHY you would want backwards compatibility from a business standpoint as the Xbox 360 users would essentially be locked into the next Xbox's platform.

However, if it drives up the price then I'm not for it, I would rather they spent the money on a better Graphics processor so my PC would benefit greatly from it.

With that said, The Xbox 360 and Playstation 3's CPU is slow by modern standards, especially when compared to x86, which is to be expected, they are over 7 years old.
So if they can get the IPC up substantially on the newer consoles, software emulation should be relatively feasible which would be cheaper than a hardware implementation like with what Sony did with the early PS3's.
But if anything is to go by with the PS4, the next Xbox will probably be going with a heavily threaded Netbook/Tablet x86 class processor which probably isn't going to be up to the task.

I will only get it if my 360 ever dies but until then both Xbox's will be together, it's about time i put my dusty Wii in the closet

Not everyone really cares about BC and its to have it as an option. I wish I could connect my PS2 Slim to my PS3 just for HDMI picture, but i can't do it.

It makes sense to buy a stand alone 360. But are stand alone 360's getting a price cut? If the Stingray is $99, I don't think the 360 S is going below $199.

I think sometimes in the next 5 years you could find a regular 360 for 99$ though.

ps3 dongle? Wtf is that??

It is an interesting ponder-able. I would prefer just to plug in my X360, but I might be letting that find a new home a year or so after I get a 720.

So would it just be like a little flash drive that plugs into the back? Or something bigger - perhaps with an included Kinect. I wonder why they would sell a new device without a Kinect as the want to go to that Natural User Interface. I wonder would they release the 'sting ray' without at least voice response?

But could it upscale the graphics? It might be worth it then. I can't express how disappointing I was to learn the WiiU doesn't upscale Wii games, but if it did that, it wouldn't sell as many WiiU games.

So right now, no, but after a few years. Only I want to play an/my old game(s), or there aren't enough good 720 games.

Vote: Unlikely, but not Never.

You're not familiar with this rumor I guess.

Microsoft is going to sell a no disc drive "mini" xbox 360 for $99. This is a fully functional XBOX 360, it just can't play discs. However it is also designed as a companion app to the 720 to allow bc. It's hooked up/plugged in so that the 720 controls everything. It's equivalent to having native backwards compatibility at this point. No emulation is used.

Definitely not. Once the new gen comes out I'll go with that and never look back. I'll only have enough time to play the current games anyways.

Now if the Xbox Mini offers other valuable features that would work great with the Durango I might go for it.
