It seems Xbox live is having some issues at the moment, I wonder why... :)

Well done Microsoft! Great conference overall.

Lets hope that Nintendo and Microsoft serve as examples to Sony, so ps4 becomes BC as well. Eliminates the 'need' for those damn remasters. And I wouldn't have to buy a ps3 to play my ps3 games if I someday end up buying a ps4 (yeah I own games for a system I don't own)

Your rply is confirming that his opinion is right, Because the hardware or i say the architecture of Xbox One  CPU is too different then  Xbox 360,  it's imposible to directly emulate the game's,  unless it's runing on Super computer ( a very powerful spec) and i doubt even Intel core i 7 with 8 core able to emulated, more so on Xbox One. So maybe it's posible that the games is just a raw port like PS2 and PS1 games on  Playstaion Network that need to be download it.

What?  Oh, I think I follow.  So you are saying Microsoft will convert every game for the developer?

You don't need to emulate the exact CPU etc, it's all within DirectX, so you just let that run. 

Fun Fact the Xbox 360 is basically a super computer from a few years earlier (eventhough it's 10 year old hardware.)

Actually, several of the games have been on Xbox Live Games for Gold, so you have them even if you only have a PC and just clicked 'download' when the game came out.

Not sure if you always have access to the game (as in the 360) or only while you have Xbox Live Gold (as they are on the Xbox One and PS4.)

I remember so many PS1 games being virtually unplayable (All of the FF remake discs had a knack for freezing at certain points, effectively prematurely ending the games.). By the time PS3 came out (I got the MGS fat version.), I was mostly over it. I actually had the same problems with the discs that were problematic on the PS2. I think it means more to platform switchers than anyone else, because having no history with the library makes BC the perfect opportunity to catch up.

It's not that simple,  direct X worked on X86 CPU but not on Power PC games from Xbox 360, If you saying Xbox 360 is Super Computer, then it will become more imposible for Xbox One to emulate Xbox 360 games even on software level, the cheapest way is to add Xbox 360 CPU on every Xbox One and the expensive one is to make Xbox One CPU the same with  Power PC architecture but more powerful.  But i guess we just have to wait and see how does it work, but my guess is not emulation (sofware ) but simply port like how SONY did with PS2 and PS1 games on PS Network.

The Xbox One is many times MORE POWERFUL than a Xbox 360.

The Xbox One CPU is different than the Xbox 360, runs at a lower rate, but still much more powerful.  (The CPU on the Xbox One also runs a little faster than the PS4 and NO the Xbox One is not a Power PC it's an AMD 8 core).

All Xbox, even the 360, run DirectX - it's where the X of Xbox comes from 'The DirectXbox'  so yea, even the Power PC used DirectX. 

Microsoft is traditionally really good with backward compatibility - so much so that it's held them back.  

A welcome move but Nintendo are running rings around them on this, it should have happened day one
and 100 games is only a portion of the 360 library.
Surely if XBone had a better library we would care less about this?

Not a big deal to me but whatever man, some people just like to play their last gen games.
