The launch event of iPad 3, or iPad HD as some have claimed, is just around the corner. Scheduled on March 7th, it will pretty much satiate all the inquiries of Apple fans around the world. But that is not to put an end to the rumor-mill – not yet. An analyst from Sterne Agee has now stated that iPad 3 will come a number of superior specs, over it’s earlier sibling, and will be a robust refresh for everyone waiting for it. Shaw Wu said that based on his sources from inside Apple’s supply chain, iPad 3 will feature high-res screen, 4G LTE wireless and support for Siri.
