Indeed, the SP count in GTX650Ti seems odd and that 1152 GPU-z (if not photoshoped) could be from a GK106. I would be more than surprised if GK106 exists and could be launched in a card as soon as this month.
But, if you think that in fact the 660Ti is a card competing in reality with the 7870 and not the 7950 regardless of the performance (this is the hierarchy) then a smaller and more power efficient GK106 can take on the 7850 and 7770. Seems reasonable.
