Back of the napkin numbers (ignoring architecture and production costs for now):
Base console - $499-$599
cpu/gpu module - standard ($149-$199), pro ($249-$299)
(5 years later) late gen cpu/gpu module - standard ($249-$299), pro ($349-$399)
- standard "couch" gamers aren't interested in PC gaming
- previous console pricing trends tell us the next generation consoles will be anywhere from $99-$149 more expensive than this generation
- the late gen modules should be were console makers ideally start to recoup a lot of the original costs they had to eat in console production because this model avoids the development of mid-gen hardware. The late gen price point is also lower barrier of entry for someone invested in their platform without the need to buy completely new hardware.
