I too am waiting for the new architecture to come to market but in the mainstream form. I think the misconception here is that NVIDIA released Titan (GK110) as what will compose the 700 series high end. I have consulted the white papers of the GK110 and the only differences, and Nvidia's concerns, lie in the HPC and workstation market. They added: Hyper-Q, GPUDirect, Dynamic Parallelism, and 255 threads/register vs the 63 on GK104. The die size is also gigantic: 561mm^2 compared to the GK104: 294mm^2. If you consult the matrix of data on the wiki: http://en.wikipedia.org/wiki/GeForce_600_Series
you will also notice the bit width of the memory bus is 384 instead of 256. So minus the new architecture features, the Titan is a GTX 690 on a single chip and it's designed to have DMA to other chips via network connections. Recall back to 2007 when the G92 was released as a 8800 GTS 512 flavor, a GF9 series in a GF8 badge. In a complementary way I could see early 700 being built on poor performing Titan chips and then a die size refab to GK11# to compose early 700 and then high-end 700 using Maxwell. This way they profit from the new arch and take advantage of Titan chips that don't meet spec, just as CPU manufactures do. ALL entirely hypothetical but the facts are here and would allow them to roll out 700 this year, or come up with a completely different naming scheme for GK110+ offspring.
