AppleInsider is today reporting on a note sent by investment firm Piper Jaffray to clients based on Apple’s outlook for the rest of 2008 and 2009.

During yesterdays financial conference call Apple stated that it expects gross margins to be down from 34.8% to 31.5% in the current quarter (Q408) with a further decline to 30% for fiscal 2009.

While Gene Munster of Piper Jaffray acknowledges that Apple is always conservative in its outlook, he also expects Apple to cut prices of existing products to maintain sales.

“We believe there is an 80% chance Apple will introduce redesigned MacBooks and possibly new MacBook Pros at lower price points,” the analyst wrote. “Specifically, Apple may re-enter the $999 price point (currently $1099) with the MacBook, or test the $1,799 price point with the MacBook Pro (currently $1999).”

Munster also spoke about iPods, he expects a “slightly redesigned iPods” that will include “lower-cost touch-based iPods” just in time for the holiday shopping season.

Piper Jaffray maintains a buy rating on Apple with a price target of $250.
