The 26650 cell size is a standard size, which is why many cells conform to it.

Regarding the lower voltage of A123 vs these Sony cells, these Sony cells also weigh about 20grams more each. 5s2p A123 (16.5v nominal) weighs 700grams without wire, and 8s2p Sony (14.8v nominal, I'm assuming) weighs 720g without wire. So the A123 will take up more space, and have slightly lower capacity, but weighs less and will be able to charge faster.
