will there ever be a day when a home console (besides anything made by SNK) will harken back to cartridge type media eventually? the hurdle has always been that memory/etc. is expensive, but with prices on things like flash memory/etc. dropping all the time, do you think we will ever see games housed on something similar, but non-volatile?

or is CD/DVD-based production simply too cost effective that no medium will ever replace it any time soon?

i'm interested to see what people will think the next "standard" format will be. something the size of a hu-card that holds a gig? microdrive-sized HD's as cartridges? on-demand downloads, so there is no media to manufacture or distribute?
