Despite the fact that the Galaxy S III supply is rather low at the moment, Samsung’s mobile boss JK Shin predicts that Galaxy S III sales will exceed 10 million in July.

Neither the Samsung Galaxy S II nor the Galaxy Note were able to achieve such fast market penetration, but neither the Galaxy S II nor the Galaxy Note were the most pre-ordered Android phone in history.

But that doesn’t change the fact that most users are unable to purchase or pre-order the 32GB version of the device, according to Reuters. In fact, Sprint has had to push back the launch of the device because of low supply from Samsung.

“Due to overwhelming demand for the Galaxy S III worldwide, Samsung has informed us they will not be able to deliver enough inventory of Galaxy S III for Sprint to begin selling the device on June 21. We are working closely with Samsung on a delivery schedule to support our launch,” reads Sprint’s site.

It’ll be interesting to see the convergence between short supply from Samsung and a brand new device from Apple. The iPhone is Samsung’s greatest threat in the mobile realm, and the company smartly gave itself a three-month (or so) head start before the next iPhone is unveiled. But with short supply surely slowing the momentum of sales, Samsung may not get everything it could out of the Galaxy S III.

In either case, the GSIII will still sell just fine and surely break some new records for Samsung. Plus, Samsung went out of its way to avoid any patent litigation with Apple this time around.
