As others have said... try to get along with it if you can... the new 7d2, if believed, is expected to have a 24mp sensor... I would bet, although not a lot, that the 70D would have a similar sensor... SO... I know technology over the last 2-3 years have improved, if you are expecting superior noise handling with 6 additional megapixels, then i would have to say your sadly mistaken. It would be something for canon to make the noise and IQ the same as the 18MP cameras with the increased density of the sensor. IF you feel limited with the 18MP... you may not get better results with the 70D. While the 6d, as a camera, looks pathetic on paper, in reality it seems to do quite well on reviews. Anyways, good luck.
