Will a SPECK brand iphone 6/6s case fit an iphone 7?

I'm debating on upgrading my phone to either a iphone 6s or an iphone 7, and already have two cases that I bought a while ago since i thought I was set on the iphone 6s but now my mind is changing. One of them is the speck 'grip' model and says "for iphone 6/6s" on the box, and the other is a speck case by jonathan adler, and also says "6/6s" on the case (since I'm assuming both were made before the 7 came out). Does anyone know if they will fit? Id hate to have to buy new cases cause i really love these.

It's about a 50/50 shot. The phones are the same size and the buttons are in the same place, but the camera on the 7 is bigger. Some 6/6s cases the cutout for the camera is big enough to allow for this, some it's not.
