The Xbox One kinda reminds me of a throwback to the original Xbox with the boxyness and lack of rounded corners. The kinect version 2 and the redesigned controller appear a tad bulky. The reveal was mostly about the features and hardware with mention of the upcoming Halo T.V. show and a partnering with the NFL. Microsoft showed how well you can switch between functions and a brief display of recording gameplay. All in all we saw the console so its a win in my book and I suspect that we will see what the next Playstation will look like before E3.
Here is a hardware comparison pulled from Joystiq.com

微軟在發布會上只簡單提到Xbox One主機的規格，8核處理器，8GB內存，但是並沒有公佈詳細的信息。隨著拆解的進行，Xbox One主機的處理器規格也逐漸浮出水面，這個8核處理器實際上還是AMD的Jaguar低功耗架構，跟索尼PS4類似，但是規格和性能恐怕比不過PS4。
Xbox One的主機處理器也是從AMD的APU產品定製而來，8核心實際上是2個四核模塊組成，每個模塊共享2MB L2緩存。
內存方面，Xbox One和索尼PS4都是8GB容量，但是微軟比索尼要保守，相比PS4的8GB GDDR5內存，Xbox One使用的還是DDR3內存，另外為處理器搭配了32MB的eDRAM嵌入式內存（Xbox 360上的是10MB），不過內存帶寬上PS4的170GB/s要大大領先於Xbox One，雖然後者的實際帶寬尚未確定。
最後，Xbox One的CPU和GPU也共享同樣頻率的內存，但是設計很有趣，他們不需要互相複製數據以便共享，更像是傳統的PC運作那樣。
Xbox One使用的APU的TDP功耗為100W，比Xbox 360上使用的處理器TDP還要高，不過製程工藝是28nm的，所以每瓦性能比上還是要比前代更高。
Xbox One的GPU也沒有詳細信息，CPU和GPU頻率也未可知，之前的傳聞稱CPU頻率1.6GHz，GPU頻率800MHz，性能上恐怕跟PS4的1.8TFLOPS有一定差距。
