I read a rumour last night (and I don't put much stock in rumours, but that said it's always interesting much like gossip is) that the next Xbox may not have a disc drive of any sort.
One of the things that make me question this rumour is the fact that I doubt Microsoft would be so short-sighted as to cut off backwards compatibility with the Xbox 360 and the vast library of games they already have available. This would be very counter-productive indeed.
There have been a slew of articles around the interwebz already that Microsoft will be continuing the use of IBM's POWER architecture and again AMD (ATi) will be providing the graphics hardware for the new Xbox (which may be unveiled at E3 this year alongside Sony's upcoming Playstation 4). Why keep all the elements that enable backwards compatibility and then take away the disc drive (and subsequently the means) that enables one to play their original games?
Another rumour is that Microsoft may be using a subset/version of Windows 8 for the new Xbox. This sounds highly plausible to me since Microsoft's new mantra is "Windows everywhere". We already know that Windows Phone codenamed "Apollo" will be the Windows 8 core, we now know Windows 8 will be running on ARM also. Why not the Xbox too? It makes sense doesn't it?
If you're curious, check the TD Daily article I spotted this rumour on here. Thoughts anyone?
