Even with the price increase (which we don't know the quantum in Canada yet) the C7 would still be no more than the C6 for a comparable car. Also, from what GM has said, the '15 Z06 will be similar to the '13 Z06 in price.
I think they launched the C7 with a purposefully low price for marketing reasons but always intended to adjust it. To put it in perspective, my 2LT Z51 with all of the extra stuff was $70,265 including freight. The comparably equipped '13 GS would have been $80K 'ish. Even with the price increase, the C7 will still be in line with the C6 pricing. I think the '14s up to now have just simply been smoking bargains
