Arguably at this point some of the earlier stories and interviews possibly make sense
e.g.

They said that 7900 series would be the mainstay of the product for the rest of the year, they didn't say there wouldn't be any additional models to the 7900 series though.
Given that 7970 is now a 13 month old product, and presumably would have been in production for a bit longer than that - maybe yield has improved so much that they can could cherry pick a 1.2Ghz core part for a single gpu product 7980 maybe?, and 1.1Ghz parts for a non-limited edition 7990?
Anyone have any meaningful benchmarks of a
[email protected] or thereabouts - would be interesting to see how close to a stock titan it would get.
EDIT: Have just looked for some benchmarks and between 1.2Ghz and 1.3Ghz gets between 10-15% over a stock Ghz Edition (Titan being on average ~20-25% faster than Ghz). If the new 13.3 drivers (or whatever they end up being called) have the promised performance boosts, then such a card could sneak ahead of the Titan.... but lots of IFs.
