That's how I've always planned to get my EVO View and the EVO 3D we're giving away (my personal one will come with a monthly bill), so finding out the official full prices of both devices has been on my to-do list for a long time. The EVO 3D's off-contract price has been seen fluctuating recently, presumably due to third parties needing to make a profit, but Sprint has finally just confirmed to me that the official unsubsidized price is $549.99.
The bigger EVO View will command a bigger price of $649.99 when purchased without a contract. This is less than I expected given that the subsidized price is $200 more than the EVO 3D's on-contract cost ($399 vs $199), but it may have taken itself out of the game, as competing 7-inch Android tablets can be purchased without a contract for less than that.
Amazon is still selling the off-contract EVO 3D for $469.99 with an estimated delivery date of June 28th, but if you must have the new phone on launch day, then you'll get the best off-contract price at Sprint.
