Apple ups iPad shipments to 8-10 million for calendar year 2010?

According to Katy Huberty at Morgan Stanley (who has an admittedly spotty record), Apple is almost doubling its production of iPads to 8-10 million for calendar year 2010.  That up from an initial estimated run of 5+ million.  Other findings:

• Suppliers now expect to ship 2.5 million in the first three months alone (March to May), considerably ahead of Huberty’s estimate of 750,000 by the end of June.
• Shipments are not sales, however, and Huberty is sticking with her sales estimate of 6+ million iPads in 2010. The Street’s consensus, she says, is closer to 3-4 million.
• Each incremental one million iPads shipped, by her calculation, equates to earnings increases of roughly $0.25 EPS.
