Looks like a dual speaker to me.
Definitely. In a way, I'm glad there are two speakers, though the single speaker of past models had a good bit of punch to it. But I also can understand why stereo is fairly pointless. The stereo effect will only work properly in portrait mode, making it useless for movies in widescreen. Plus, if I want good sound quality, I'll just use headphones anyway. Dual speakers are probably more useful on the Mini because of its smaller size.
