It would probably be wise to build the PS4 with a very similar architecture to the PS3 with only marginally improved hardware to keep the console affordable to consumers and profitable for Sony. The Blu-Ray drive's read speed, system memory and video card would be the components needing the biggest upgrades. Improved middleware/dev kits, a more streamlined OS and software B/C for all previous Playstations would also be good investments. Personally, I'm not sure if it would be advantageous to be the first to the market for the 8th generation. Doing so would shorten the PS3's lifespan and they could wind up in the same situation as Sega as a result. If they launch too late they could end up in a similar situation to what they're in now.
