I ordered a XPS420 with the Spring Savings deal. $1498 loded with a 22" screen and 2 DCT tuners on Sunday 3/30/2008. The Order Shipped out on Monday (heck of a turnaround for a custom built system), but like you, my tuners are not expected to ship until 5/25/08. Ouch!
I called Dell and they have a 21 day return policy from the receive date of each order (the tuners are a seperate order). I wanted to make sure that if a tuner arrived DOA, I wasn't going to have to eat it, because of the big ship date differences. I explicitly asked about support and return/replacement on the tuners and was ensured the tuners would be covered by Dell if withing 21 days.
So what the heck is up with ATI and their DCT production? Either they are having some serious problems with the hardware, about to update the line to a newer rev, or significantly underestimating the demand for these products.
I'm hoping Ceton gets their stuff ready soon and I can just refuse/cancel the DCT order. I was just going to order the XPS 420 w/out tuners, but wanted to make sure I got the Vista PID for DCT. Come on Ceton hurry hurry!!!!
