I think I mentioned in the Bioshock thread that this is pretty much the only game I've felt I needed for a good while, but that's mostly because it's Metroid. As such, I know I want it and, aside from stupidly watching an E3 trailer that showed me too much, I refuse to read anything more on the subject because total surprise on the littlest things, even mechanics, are worth their weight in gold right now.
Sadly, with my current schedule I probably won't really be able to play until the weekend after its release unless I spend a couple nights not sleeping very much. That'd probably be a bad idea with this lingering cold I have, but I rarely make healthy decisions when Metroid is involved.
