For those of you contemplating a new laptop purchase for next school year, the latest rumors indicate a new MacBook Pro to be announced in June and a new MacBook sometime in the third quarter of this year. Keep in mind that rumors are just that. Even the same rumor from two different sources is only slightly more reliable than the answers given by a Magic 8-Ball.

The new MacBook Pro will supposedly come with a spiffy new LED backlight display that is brighter and more power-efficient than existing displays, according to a rumor at Think Secret. The same rumor puts the Mac Book refresh at sometime in the third quarter, which would be unfortunate timing for students who start in August.

AppleInsider notes that Intel’s eagerly-awaited Santa Rosa chipset is now available, and that “Apple’s first notebook design to incorporate Santa Rosa features should arrive in the form of an update to its 15-inch Mac Book Pro during the second quarter of the year, which should pack a faster 800MHz frontside bus and second generation Core 2 Duo mobile processors ranging up to 2.4GHz with 4MB of L2 cache.”

Steve Jobs has already committed to a wholesale transition to LED displays, and since laptops have been leading Apple’s marketshare growth, it makes sense that the new display technology would be ushered into laptops first.
