When is comes down to it the visuals from a large part of the immersion fact.  The advances in CPU technology is powering ahead.  Thats why the 4+ year old consoles are loosing ground to PC's.  The ability to generate graphics and the ability to display them will undergo dramatic growth paths over the next period.  The PC's leading that race right now.  

According to Nvidia's CUDA GPU roadmap released last year at Nvidia's GPU technology conference, the 28nm "Kepler" generation of chips would appear in the end of 2011. However, Nvidia will unveil its 28nm GPU architecture 2012 and 22/20nm sometime in 2014, respectively, one year later than originally planned, possibly due to low yield rates of Taiwan Semiconductor Manufacturing Company's (TSMC) 28nm process as well as lower-than-expected performance of the Kepler chips. The generation chips will consume "a little more" power than the current generation Fermi chips Fermi chips but they will also be faster, according to Nvidia chief executive Jen-Hsun Huang.
