Are the next gen consoles upgradeable?

I am not talking about just swapping out the hd's for an ssd, that's pretty common knowledge.

I want to know if they would allow for a drop in upgrade a couple of years down the line.. e.g dual graphics crossfire with a 240 etc

I am pretty certain that the dual graphics issues with latency / frame pacing are only specific to windows / direct x so I think that dual graphics style upgrade may actually be viable for the consoles...

This is just a random thought popping through my head on my train journey home :)

no, the consoles will not be upgradable. Their hardware is proprietary. It may be AMD, but it is still hardware that is unavailable to the general public. Following that route, they will never off an upgrade path for the consoles. If you want an upgradable console, steam machine or PC.

the PS4's hard drive is upgradeable thats about it. you put SSDS and HDDS in it but they must be in the 2.5 inch size which is the laptop hard drive size. the Xbone is a Closed System.

i didnt mean custom diy upgrades...

I meant that do they have the built in capability on the pcb board for proper IO expansion (e.g pci interface or similar) somewhere down the line by either sony or microsoft.

It was just a random thought.

The whole point of a console from a developers point of view is that you always know exactly what specs it will be running. This allows you to really customize the performance of your game to make the most out of all of that power and utilizing supported architectures and instruction sets. If you were able to upgrade your console... It'd just be an overpriced computer with a shitty UI and locked down features.

In all honesty, that's what consoles are anyways.

Nope, everything is part of the mainboard. No sockets or standard IO. 

Although on the 'Bone, it appears as though the mounting procedure for the CPU heatsink is standard. So maybe different cooling as long as it was low profile?

Damn, i was expecting that but hoping that one of these days a hardware console maker would get a clue.

The only reason sega cd, 32x's later expansions failed was because they were never built with expandability in mind in the first place.

You would have thought that a planned expansion 5 years into the lifespan to give the platform a kind of 'refresh' and prolong lifespan would have been tempting to either ms or sony.

Still people probably equate console expansion kits with failure.

Yeah there's no point, all the games are set to run at dah dah dah and and at a fps of such n such. If you replaced it's approximate 7770 with a titan it wouldn't suddenly run extremely well, it'd still be dah dah dah and such n such because they're locked at those settings and there's no way you could change them. Unfortunately.

Definitely not. Ignoring all of the technical and business reasons against such a move, the only reason you'd want to upgrade the technology would be to make even more advanced games. Well then those games wouldn't work on the people who don't upgrade their consoles. Then developers will have splintered their install base. At that point it becomes functionally identical to just releasing a new console.

Someone needs to put a Noctua in an Xbone! Anyone?..............
