I'd get Heavenly Sword and wait for the DualShock3.

Do you own a 360? If so, CAG is reporting that Gamestop just dropped the Darkness to $30.

Yep, that's what I did.

I don't have a 360, but I decided to hold off on The Darkness for now. Seems ripe for a price drop.

I did get Rainbow Six: Vegas for $40 at BB, along with the new Ratchet & Crank, NHL 08, and Elder Scrolls. It doesn't look like BB was carrying the Game of the Year edition of Elder Scrolls, but for a $30 price difference I can do without Shivering Isles. Isn't that content that can be purchased through PSN anyway? I thought that's how it was with the 360 version.

I actually did have a 360, but I unloaded it before it had the RROD. Sure enough two months later my buyer told me it died. But since the warranty was extended he was OK.

I will get a 360 if and when there are confirmed models in stores without the design flaw that causes RROD, and I really liked XBL and XBLA.

360? Yes. PS3? Nope, never. But I did read that an expansion disc would be coming seperately. Besides between the original game and the KotN expansion included in the PS3 version, you won't be lacking in content.

Does the GOTY include all the extra content besides Isles and Kot9, like the Pirate's Cove, the wizard's house, horse armor, etc?

Locking for length.
