I'm pretty sure this phone will have the Sprint premier early availability. They've done it for every major smartphone, and even for the Samsung Replenish.
This is a strange launch.
Every pre-order in the past could be done at Sprint dealers, Radio Shack and Best Buy. This one is only at Sprint corporate stores.
We know that the delay from the original planned launch announcement on May 26th is due to the fact that none of their plants can keep up with Asia and Europe sales yet.
I am betting that only local corporate stores for pre-order is due to the fact that Samsung still is struggling to get enough phones to market.
If you want one, go to a corporate store and pre-order now. It took weeks before you could find an EVO 4G if you missed pre-order. This may be just like that.
