It's been discussed over many pages and threads already, but to answer your question...
It's still a rumor. Though, has gained more chance of happening.
It's been said that Apple will release a refresh of the Macbook and Macbook Pro during the time that Intel releases their new "montevina (?)" microprocessors.
They just delayed the release of the new chipset to early/mid July, so hopefully, a new Macbook/MBP can be expected during mid-late Q3 (July-August/September)
Though, keep in mind, It is still a "rumor" but somewhat likely to happen.
I'm waiting ;D
Best,
