I'll be posting the rest of the Spaceworld news later on this evening, but to tide you over until then, here's a link to Cube.IGN, where they have posted the first in-game footage from Metroid Prime. It's woefully short (blink and you'll miss it) but it is direct-feed, and features some first person and third person action. Also of note is this progress update from Shigeru Miyamoto himself.
