Okay I'm gonna just say it, I think it's a horrible idea on so many levels here's why:
The Material:
Yes it's more durable, but look at The incase sliders or any other matte case you find, it holds up well, but gets scratches from even fingernails. It gouges and for those with sweaty hands ( not me ) it ends up looking smudged and dirty in a matter of weeks.
BIG QUESTION:
What's the other color gonna be? WHITE? Have you seen what happens to white matte, a guy on here had bought a case in matte white and after only ONE DAY it had dirt smudges gathering all over, it looked like hell.
Design:
Where is it? Apple's design team just doesn't take a year off and say,
"Just go with Matte and a darker bezel, BAM we're done!"
Forget the material for a second, it's the same contoured body as the 3G. Yes they subtly change design sometimes but this is just a bezel change and a material backing? Especially when the competition is just starting to get heated (Palm Pre, G2, and the Storm), Apple needs to SHOW us why they are different.
Mass Consumer Attraction and Advertising:
Besides us, how do you see this change in the eyes of the everyday consumer. Apple loves sexiness and attracting attention, you all know that. This sets them back quite a bit with the main audience no matter how much better it may be than the glossy plastic. As if that's hard enough how is Apple going to show everyone how different and new it is if it looks like a dull version of the 3G? I know WE know the specs, but they would be missing the audience in which they make the most money.
Ebay:
Didn't we see these sold on eBay already? With the same pics and one with a 32gb tag? It would seem pretty easy for a foreign manufacturer to make these at a cheap price.
FCC:
What is the stamp doing on there already? We know when the FCC receives and reports a new product like this. Also someone pointed out the height of the matte looks shorter than the actual 3G.
I know it's a dream for some of you guys here, but from a business standpoint and a consumer's, I don't think these pictures are the real iPhone.
or maybe I'm just talking out of my butt 
WE'LL SEE COME WWDC
