Because the true succession was 40D -> 50D -> 7D
The 60D is closer to a "slightly improved" 600D. Is Canon allowing Nikon to be alone? Hardly.
I don't agree... true, the 60D lost some minor features of the 50D but the gap between those two cameras is very small compared to the 7D.
The xxD line has 9 cross-type AF points, compared to the 7D with it's 19 cross-type AF points. So, if a 70D would be the successor of the 7D, what type of AF will it get? An improved version of the 40/50/60D or an improved version of the 19 cross-type AF of the 7D?
And if this would be the case and the 70D would replace both 60D and 7D, which means also that the 70D will be priced similar to the 7D (~1500 US$), than there is a hugh gab between the 60D/7D successor and the xxx/rebel product line. I don't believe that the xxx/rebel line (1 cross-type AF point) will receive the AF of the xxD product line and I don't believe that canon will leave such a gab in its product portfolio.
So if those rumors are true, then something has to fill the gap. And don't forget, the rebel name is only used in the US/Canada. In other markets the rebel name is unknown.
Ugggg, reading this, if its true and this is the plan, it does make it very hard on emerging pros without big pockets. The 7D line commanded at least a bit of respect, so its really hard to not see it as a downgrade to move to a XXd from a Xd. Plus,at least given the old price structure - the 7d filled a niche in both capabilities and price (fitting nicely between the 5D and the 50/60D.
If this is true then we'll have a huge gap -
$1500 70D
and oh, if you want anything better:
$3000 5dmkiii
I guess the only real hope for those in my shoes is that it becomes a buyers market once the 5dmkiii is out on 5dmkii's (which mkii users probably don't want to hear).
I am truly hoping that canon doesn't force the issue like that and leave such a big gap in price and quality. There's gotta be room for a 1.6 crop semi-pro body, something that can have its price point land at $1900-2300?

a merged line, 60D/7D falling in at $1500??? I'm just having a hard time seeing that as being an actual upgrade on the 7D. If your on the 60D, then yes a 70D would be a nice thing to look forward too. But damn you canon, thanks for forcing my hand - if there's no viable upgrade to the 7D in the 1.6 crop world - its timeto go FF and incur all the other costs of doing that (replacing my 10-22 with a 16-35, then adding something in the 300mm range, while putting filter upgrades on hold due to the new 82mm filter thread size needed for the newer L series lenses......)
Its a move i need to make anyways, but damn you canon if this rumor is true cause that really forces my hand...
