Kotaku - Sources: Sony Is Working On A ‘PS4.5’

[CosmicSex]

"Our sources aren’t sure when this upgraded machine will ship to consumers, nor how much it will cost. The PS4’s price dropped from $400 to $350 last fall, and one source indicated that this new ‘PS4.5’ could let Sony keep selling PS4 hardware at a higher profit margin for $400."

Does anyone really believe that a PS4 with a 4k capable graphics card would be $400 and still generate profit?
