This definitely won't be the 70D. Most likely a higher-end model, as Canon will surely try to capitalize on the image quality improvements that the new process will bring.

So you are assuming that the new process will be better simply because it allows smaller structures?

Image quality is not something which is positively affected by smaller sized structures, it is affected by the quality and uniformity of the generated cells (each cell would be produced by several structural elements of the new process), the amount of space lost to support circuitry (again smaller may be better) and the isolation of cells/support circuitry against each other and outside effects (which is much much worse on smaller structures, that's why NASA was looking for old CPUs manufactured on fabs long since gone and impossible to reproduce using newer fabs).
