Well you may accuse me of being a bit of a spoilsport, but I don't think the Mac mini power adapter recently being added on The Apple Store is anything more than a 50 dollar power cord. No, Apple Insider, I don't think this is foreshadowing anything at all.
If anything, Apple will probably just release Front Row for all Mac models and leave it at that. You want to rumor monger? Fine. Go pontificate about what we'll see in an Intel flavor in January.
Update: Apparently Apple Insider took down their post about the adapter. Move along now, nothing to see.
