According to a Mac accessory maker, Apple is gearing up to release a 15-inch version of its popular MacBook Air ultra-portable laptop in April, reports British tech website Electricpig .

Rumors of Apple altering its MacBook line to resemble the MacBook Air are not new. In July of last year, after the launch of the new MBA, MacRumors.com reported that it was tipped off by a source that Apple was working on a larger 15-inch MacBook Air.

The source says that it's not clear if the new MacBook Air would replace the MacBook Pro.
