I've worked on games running "spike beta" aka "The Pin" system. It has a lot going for it and will mean big changes for service. Replace instead of repair will probably be the norm. The multiple driver board architecture is similar to what mmr is doing. Game code is on a insertable compact flash card. The impact to ease of manufacturing and ability to outsource sub assemblies will be significant IMO.
Some may not like the change but this is a logical and necessary transition me thinks. Smart.
