Agree on how poorly phrased this rumor is.
I still don't understand how a 22mpx full frame camera from Canon is expected to compete with a 36mpx camera from Nikon... Different leagues in terms of resolution. Also, with Nikon strongly rumored to be offering a camera without an AA filter it will distance itself from the new Canon entry even more so.
It looks like Canon has decided that they will make more money from the people who need high ISO, rather then from the people who need a higher resolution.
If Nikon does indeed release a sensor with a maximum (analog) ISO of 6400, it means that either:
* They think the opposite of Canon (which is weird considering that so far they mostly released low resolution sensors).
* They (/ Sony) don't trust that the technology they have can go up to a maximum (analog) ISO of 51200** (like Canon has in 1DX), even at a low resolution. So, the only thing they can do to compensate is to increase the resolution to 36 MPs (and keep the noise at the level of D700). Certainly, by themselves the numbers don't mean anything beyond speculation, so we'll have to wait to see.
Alternatively (and highly unlikely), if we ignore the maximum 6400 ISO rumor, maybe Nikon found the magic recipe and can do both high resolution and high ISO.
** Even if the 3 stops in ISO difference is there only to allow people shooting in JPEG at a very high ISO, since Canon said that DIGIC 5 gives 2 extra stops, it still leaves 1 stop of analog advancement.
