Technical and efficiency arguments aside, I think most buyers will consider this a very desirable feature, and I find it hard to believe that Tesla or Cadillac will be selling vehicles requiring plugs in ~2016, if Nissan and Toyota will be selling vehicles that "plug themselves in", at a small fraction of the cost of the big-bucks "Luxury" BEV/PHEVs.
...What’s in store for future PiPs? Ogiso had this to say:
“We have been listening very carefully to Prius PHV owners and are considering their requests for additional all-electric range. We have also heard from owners that they would like a more convenient charging operation. In response, we are developing a new wireless/inductive charging system that produces resonance between an on-floor coil and an onboard coil to transmit power to the battery, providing charging without the fuss of a cable.”
Ogiso adds that verification testing will be conducted on wireless charging in Japan, the US and Europe in 2014...

...Nissan Motors told reporters at a product preview of future models that the company now has plans for five plug-in vehicles in its future – and that Nissan is preparing inductive charging for all of them...

BTW, I was visiting a friend in the Bay Area who drives a PIP last week.
He has a short commute, and plugs in at home and at work to get most of his commute miles on E.
It occurs to me that he probably plugs/unplugs his PIP ~ 70 or 80 times a month, while I only do it ~ 20 or 25 times, on average, to drive ~ twice as many miles on E.
So, maybe inductive charging will be even more desirable for the short-E-range PHEV drivers, than for BEV drivers.
