If this is the case:
Is it worth waiting for Haswell? I've heard (Haven't done much research into this, apologies for my ignorance) that Haswell will bring massive performance and battery-life saving gains, and according to the image, which may be true (Consolidation of line may mirror the MacBook Aluminium --> MacBook Pro 13" a few years back).
I'm in a strange situation right now. I damaged my MacBook Pro 15" (First unibody MBP from late 2008) irreparably (Screen damage from thermoflask) so I bought a MacBook Air 11" this April, a few months before the expected refresh of the MacBook lines.
I'd really like to swap back to a MacBook Pro 15" (power gains, and if the news of the redesign is true, thinner and lighter, which is what I like most about the MacBook Air).
However, I do not necessarily have to swap now because 1) I have a MacBook Air 11" now 2) Haswell may bring big performance gains.
Opinions on this? Is Haswell worth waiting for? I'm not in an immediate need for a new MBP but would like to know more.
Thanks in advance.
