Bloomberg reports that multiple industry analysts are expecting Apple to cross the 600,000 sales mark for the iPad 2 during this launch weekend. This compares to the 300,000 WiFi-only original iPads sold on launch day on April 3, 2010.

Brian Marshall, an analyst at Gleacher & Co expects Apple’s second generation iPad to “outpace” the original model. Tim Bajarin, an analyst at Creative Strategies Inc. and Rodman & Renshaw LLC and Piper Jaffray & Co. concur.

The two leading reasons for more iPad 2 sales have to do with more stores selling the device on opening day and the addition of the white model.
