GameStop has reaffirmed its forecasts for the first quarter of the financial year and its overall sales and earnings guidance for 2009.

“Based on current retail trends and the strong sell-thru of new video games released in February and March, such as Capcom’s Street Fighter IV and Resident Evil 5, Microsoft’s Halo Wars, Sony’s Killzone 2, along with an exceptional launch of Nintendo DSi, GameStop is reaffirming its first quarter comparable store sales guidance of flat to +2% and earnings per share guidance of $0.40 to $0.42,” the company said, suggesting it isn’t overly worried by the slump in US software and hardware sales during March.

“Full year comparable store sales guidance remains +4% to +6% and full year earnings guidance is still expected to increase between +18% and +22%,” GameStop added.
