Somethings going to have to change, as otherwise the PC gaming market is going to take a massive hit, as users won't be able to upgrade, and fewer second hand components will be available at reasonable prices for those on a budget. More expensive systems and components mean less money to spend on games.
It's also true of the new consoles. The platforms make most of their money on games - consoles are often sold at a loss - so fewer new consoles sold mean fewer games sold. Given how expensive AAA games are to develop, that could have serious consequences in the long term.
Why do you think fewer consoles are being sold? Sony and Microsoft have sold everything they can produce. PCs probably havent paid for a AAA game since Crysis.
