Yes that is true. It seems that Nokia's desire to keep the technology under the hood is unnecessary now. There are two options now:

Case 1: 2 devices, one without haptics, other with haptics
Case 2: 1 device with haptics

Personally I think we will see Case 1 in action.

While the Japanese device in the video is most certainly technology demonstrator, it is a matter of time before others deliver their devices. So it is about time for them(nokia) to shed more light to us and to start marketing campaign.

Since I've decided not to be an early adopter (sheep), I've decided to wait for one year no matter what Nokia shows us.

Besides the haptics have to prove the durability (another 770 and 810 experience)
