I happen to know physics and what paradigm shifts are, I even read Kuhn's works :)
But a paradigm shift is not a branching of models: after the shift there's only the new way to look at things. It may include the old way as a particular case, but the old way is no longer a generally acceptable thought model.
There's no paradigm shift with the Wii: things haven't changed for that certain group of gamers we call "core gamers", nor the way we look at their wishes and spending ability. The Wii happens to be sold at those core gamers, who want to play SSBB and SMG and Zelda, _and_ at a much bigger audience that was up to this point untapped.
This is a branching, because the needs and wishes and habits of these two groups are very different, the core gamers being much more represented among the owners of the so called "HD" consoles but fundamentally still wanting the same things as ever. With all the bickering about graphics vs gameplay, these gamers on Wii or PS3 or 360 are still infinitely more alike than the people buying the Wii as a Wii Fit appendage to get some exercise, and party games for the family as an afterthought.
And no, I can't see your similitude between Arcades and movie industry at all. Console games have nowadays much higher production values than Arcade games.
Arcades are more like d'essai or gimmicky 3-D/odorama theaters. You go there to either enjoy an old classic or to interact in some unique ways with the games (moving cabins, dancing mats etc)
