That would be an intriguing product. If the CCX is now the CCD, then it stands to reason that the 8-core Vermeer is going to share the same latency advantages of the 3300X, a scaled-up 3300X if you will.
Meanwhile, the 10-core SKU might have double the write bandwidth and 2 more cores, but it'll also share the current 2-CCD [slight] DRAM latency penalty, not to mention that having only five cores per CCD places it lower than the six-core SKUs in the binning hierarchy, which might not bode well for volt/freq and speeds on that SKU especially if the 8-cores are poised to have their purported improvements.
