I have the feeling that if there is a RTX Titan it's going to be $2k or more. That is more than I'm willing to spend. No way they drop the price so soon on a 775 mm² chip.
That's how I feel about it too.
At least this generation they gave us TI's at launch, instead of releasing them after Titan cards, with close to Titan performance, for 1/2 the price.
