.....Wut? 
Well check point 5 of my OP.........

yes.  We are in the 8th generation of games.  Not 8th generation of specific company or console.  if you interpret that wrong it's not my fault.

Just your grammer was all over the place in your previous post...Would you then say game engines are a better factor for determining gen rather than consoles?
