Then it wouldn't be viable as a cost-saving measure (short-to-interim term), would it...?
I am not sure I follow you. You would need ten of those chips to get 20 GB of storage anyway, still at a cost of $17.
Maybe they will, but I hope they will have an empty 2.5" HDD SATA slot in the slim unit instead of some esoteric SSD slot. The size shouldn´t really be a problem considering that most laptops use a 2.5 HDD. That would offer an easy cheap upgrade path to large storage.Now, I do think there will come a point in the PS3s lifespan where a SSD of (what will then be deemed to be) a reasonable size will cost less than the base cost of the cheapest HDD alternative at a transparent (or advantageous) performance level for the user, but I think it's highly unlikely for it to happen within a year.
My guess is that this would correspond with the (almost) certain introduction of a "PS3-Slim" since going with a smaller form factor SSD (mini PCIe?) would offer design advantages and materials savings at the same time.
