Apple will today announce it’s fourth quarter 2009 fiscal results. Wall street and analysts alike are looking for Apple to impress and once again beat expectations.

Apple which is scheduled to announce the results at 2 p.m. pacific, 5 p.m. eastern and 10 p.m. London time will likely also beat its own forecast which it offered during the Q309 conference call.

During the Q309 results announcement Apple CFO Peter Oppenheimer said, “Looking ahead to the fourth fiscal quarter of 2009, we expect revenue in the range of about $8.7 billion to $8.9 billion and we expect diluted earnings per share in the range of about $1.18 to $1.23.”

The Street via Thomson Financial is looking for Apple to report $1.42 a share on revenue of $9.2 billion. On the sales side the street is looking for iPhone sales between 7.5 and 8 million bad Mac sales between 5.2 and 6 million. iPod sales are expected to fall between 9.9 million and 11.2 million.

It should also be noted that the generally accepted accounting principles (GAAP) rules have been redefined allowing Apple to account for iPhone revenue immediately in a quarter not spread over two years. It is not known whether Apple will adopt this model or whether the company will continue to report GAAP and non-GAAP results.
