This camera will be a 6D minus the FF sensor. It will not have dual SD card slots, it will have a 9pt af (1 cross type) and will not have weather sealing like the 7D and Nikon D7100 (though it will be partially metal like the 6D with some sealing).
I very much doubt they will stick a worse af system in the 70D than in the rebel line up. During the 40D and 50D eras they segmented by using the af system as one differentiator after all so to me it'd make most sense to put the 7D af system in there. Especially as the R&D cost will already have happened and production going well.
Why not - if rumors are true - the "thing" would cost $1,2k. In order to separate it from 7D2 they would do so. Otherwise 70D would suffer cannibalization from its big brother.
I give it 11 or even 19 af points at most. But for sure 1 SD slot. For sure for this money no weather sealing
