When the 17" got the unibody design (or, rather, when it didn't and the 13" and 15" were announced with it), Apple (it was Steve himself, right?) outright said that they would have a 17" coming along shortly once they got the kinks worked out.
They still updated the old design with new specs, and that lasted for… four (two?) months, so I see the 13" and 15" in the old case as an example of JUST that, nothing more: giving people who feel they need a physical Ethernet/FireWire 400/ODD (ell oh ell) the opportunity to scoop one up while the getting is good.
I think that once a 13" newnibody (hey, can we call them that? They're both unibodies and we need to differentiate. I know it sounds stupid; that's why I like it ) comes out, the two old designs will be dropped and, you know, they might kick the 15" retina down to the prices of the old unibody 15".
Watch me be right about that. Apple likes to use early adopters to subsidize the price of later models.
