The consumer version of it will likely launch shortly after for $700, but with less VRAM and no double precision, albeit similar performance. Much like the Titan and 780 Ti; they were virtually identical in most scenarios other than higher-res gaming where the Titan's 6gb VRAM made an impact.
Having a Titan, IMO, is partly "wow" factor and just wanting to say I have a Titan. I could be wrong, but that's how it worked out last gen. The wait is just getting tiresome because the GTX 980 is not a true generational improvement over the 780 Ti by any means. However, I still bought one (980) for the meantime, at least until we see how this Titan X/980 Ti/enthusiast consumer card pans out.
I think people like you and I, who owned 780 Tis, are partially salivating at the Titan X because it has been so long since our card has been on top, and nowadays it's becoming inadequate. GTX 980, as mentioned previously, is not really a huge improvement (other than power efficiency). I'll make do with my GTX 980 for now, watercool and overclock it, and pray that nVidia announces a 980 Ti shortly after Titan X...or cave and spend the $1350 on it.
