Following an earlier leak of an alleged MacBook Pro case, new shots have surfaced today of what appears to be a new 13-inch MacBook through the same Taiwanese site that has carried earlier leaks. The new images show an aluminum casing reminiscent of a MacBook Air but which is just thick enough to include a full range of ports (similar to those of the current MacBook) as well as a slot-loading optical drive. It also shows a space for a larger trackpad.

No photos have shown with this latest leak, though a past set showed a matching lid again like the ultraportable system.

Separately, former TechCrunch blogger Duncan Riley at the Inquisitr claims to have received details of a significantly expanded price list for a new MacBook range that adds four new price points, including a higher $3,100 option as well as a new, lower $800 price. If accurate, the rumor would reveal Apple's first-ever plan to sell a notebook significantly below $1,000 and would imply less expensive parts and potentially a new model. The announcement would come within 10 days, according to the allegedly reliable sources for the tip.

Such claims are difficult to verify and so should not be taken as fact, though introductions for iMacs and other systems have been revealed through similar price sheet leaks. Analysts have repeated predictions of a lower-cost MacBook but have so far suggested the base price would rest at $999. [via MacRumors]
