says there will be a new macbook in the 13,15 inch guise sitting between the pro and air
I love my 17 inches
For both past designs of the MacBook Pro, the 17" model was introduced later.
The non-unibody 17" MacBook Pro was introduced in April 2006, 3 months after they announced the 15" model.
The unibody 17" MacBook Pro was introduced in January 2009, also 3 months after they announced the 15" model.
So even if there's no new 17" MBP introduced at WWDC, chances are that it could be announced a couple of months later.
If anything, I think it's the 13" Pro that will be killed off. It has almost no difference from the 13" Air, and Apple has been pushing the Air branding a lot. Judging from Apple's past maneuvers, the company hates redundant products, and that's exactly what the 13" Pro is. It's a computer that's not as portable as a MacBook Air 13", but not as fast as a 15" MacBook Pro. It's only logical that they kill off this machine.
