I'm glad you like the new Metroid but so far this is my least favorite in the series due to some gameplay glitches (at least I hope they're not intentional) and control issues.
I'm looking forward to trying out Reach if it's ever released for PC. I've been trying to get anyone I know to get an XBOX360 so that I can play Halo 3 but so far everyone I know either bought a Wii or just bought a new PC. I considered getting one myself but I don't want to spend money on a new console for just two games. I already pre-ordered the new Goldeneye so I'll let you know how it is after I get it.
