AppleInsider is reporting today that Mike Abramsky from RBC Capital Markets said today, May 28th, the day the Apple iPad launches internationally, that Apple will sell around 600,000 - 700,000 iPads in the month of June. If the prediction is correct, the number of iPad sales could blow out Mac sales, which will be around 500,000 internationally in June.

"Industry contact feedback and previously published surveys point to strong international demand, supported by media reports of long lineups at Apple stores, and strong demand for iPads," Abramsky wrote. "iPads appear to be stocked out already at some stores and resellers, particularly in countries like Japan, Australia, and U.K. Online availability has been further delayed, to a vague 'June,' from June 7 (prior to which was May 28)."

He believes that Apple will sell a total of 8.1 million iPads in the 2010 calendar year, but this could be less because of Apple's struggle with coping for demand of the iPad both in the U.S. and internationally.
