Would make sense for them to time the 100D announcement late enough not to impact Q4 sales - but early enough to drive sales for Q1.
Even if they don't have enough battery packs to build 100Ds right now, they'll likely have enough volume to build them sometime in Q1.
If they push out the 100D announcement, they may risk depressing Q1 sales. While the phase out of unlimited free long distance charging might encourage some customers to order before the end of the year and get delivery in Q1 - I suspect there's a larger number of potential customers sitting on the sidelines waiting for the larger battery pack.
