I think the whole bureaucratic mess was renamed the EU somewhere about 10 years ago. Don't quote me on that though!
Yes, the little light gray patch you're talking about is Switzerland. They're NOT one of the proposed new EU entrants, although I believe there has been some discussion about whether they should join, thereby ending centuries of neutrality.
There's another non-EU country which doesn't show up on that map. That's the independent principality of Andorra, high up in the Pyrenees betweeen France and Spain.
