15.4" MacBook in 2nd Quarter 2007?

Digitimes claims that Apple will be shipping 15.4" MacBooks in the second quarter of 2007:

Apple is planning to introduce 15.4-inch MacBooks in the second quarter of 2007, according to industry sources in Taiwan. The new model will fill the gap between the company's 13.3-inch MacBooks and the 15.4- and 17-inch MacBook Pros that form its current notebook line up, and is expected to boost shipments of Apple's Intel-powered MacBooks, the sources add.

Historically, Digitimes has not been very accurate with their predictions, but a number of recent Digitimes rumors have been corroborated, if not confirmed. (LED-backlit Laptops, Apple Notebook with Robson Caching)
