LevelUp has their Part 2 Interview with Reggie, and he talks a little bit about Metroid Prime 3:

One of the things that you said–and then I subsequently I said “Is that a read-my-lips pledge?” and you said “Yes”–was that Metroid was going to ship in early 2007. And time’s running out on early 2007. Stephen says that he gives you until the end of June; once we get to the halfway point, then early 2007 is over. But I think I was fair, in term of the question that was being posed and the context of it. 

…Where is Metroid? Metroid is not going to ship by June. We’ve announced all of our games through the end of June. And the fact with Metroid is we want to make sure that that game is perfect. Unfortunately, Metroid Prime 2 didn’t live up to our expectations, it didn’t live up to Retro’s expectations–

Is that in terms of sales or the actual game itself?

From a sales standpoint. I think we were all happy with the product itself. Certainly it won quite a bit of critical acclaim, but the sell-through wasn’t what we wanted it to be. We want the sell-through as well as the critical acclaim for Metroid Prime 3: Corruption to be the best in the series, and that’s a lofty bar. To do that is taking a little bit more time than we had anticipated. But it’s coming. And it will be great.

Not till after June???  Please Nintendo, please give us AT LEAST a new screenshot!  I’m SO excited about MP3!!!  Don’t make us wait too long Nintendo.
