The AT&T HTC Titan is slated to launch in the next few days, specifically this Sunday, November 20th for $199. While the AT&T price ain't bad for such a massive phone, you just know somebody like Costco will be able to under cut that a bit.
And if you're like us, you enjoy buying massive things in bulk. The good news is Costco's will be offering the Titan right quick on November 23rd, presumably for a cheaper price (and we hear better return policy, though it's been ages for us). But if you were planning on getting the huge 4.7" inch Windows Phone 7.5 device and you have a Costco membership, you may want to hold off a few days till you hear what their offering will be.
Thanks, anon, for the pic!
