[citation][nom]gravewax[/nom]OF course it would be trouble, the reason consoles are so attractive to studios is the fixed target, they know if it works on one ps3 fine then it will work on all ps3's, if it works on one 360 then it will work on all, this gives them an exact spec and performance to target for every single player. once you start fragmenting the user base with differing hardware levels you are back to PC type gaming which means either forced upgrade cycles or the new upgraded console getting no support as all the games are targeting the lowest common denominator.[/citation]on PC there are thousands of diff hardware combo specifications. Thats why it is hard for developer to optimized for all hardwares. But if Valve limit just a few standards, then thing would not be much diff from consoles. a FIX specification for every year is still significant advantages than a console that have fix specification for 7-8yrs.
as what I expected, the Xi3 is an upgradable console.
What I am seeing is Valve probably will set the specification for every upgrades every year etc, for ex. Steam box version 2013,2014,2015 and so on. Then instead of making the console themselves, they'll open to all the board makers to do it. *ie. Asus/Gigabyte/MSI.
With the manufacturing cost and capacity from those board makers, and the games on steam = u can play on PC/Laptop/ur console in 1 client. It also mean u do not need to buy another same game again just to play on diff platform. *ie owning skyrim on xbox still need to buy PC version.
Valve is sellign their platform/ecosystem=steam, not hardware. This is one very powerful ecosystem that xbox/Sony should not be taken lightly off, because they are not against valve alone, they are against with all the board makers as well.
