With just hours before the big day, we just received word (unconfirmed, but highly probable) that the Dell Venue Pro will sell for $199.99 on contract. No word on cost without a contract, though we imagine it to be in the $550 range. The source of the price quote is none other than a Microsoft store, who will be selling both AT&T and T-Mobile phones tomorrow morning.
This sounds right as every other phone is selling for $199.99 (Samsung Focus, HTC HD7, HTC Surround) so this fits right in with the current line up, no more, no less.
Thanks, Joel K., for the tip!
