I dont think Nintendo has anything to do with any of this (neither does Sony or MS). The casuals will go wherever they think they can get the most for the least. (Wii with Motion/Party Titles, PS2 with usable out of the box DVD player, PS1 for CD playing...etc).
Sony tried to do the same with Blueray and PS3, but Blueray (or MS and HD DVD) was not even close to the scope of the DVD revolution.
This gen is shaping up to be more about gaming, as a good deal of those casuals are probably going to stay with their Wii's for the Party Games. This could all change, we will see.
