This point is unfair. Intel is ahead of everyone. You'll have to wait longer than this to see if STM will abandon FD-SOI (which I think is highly unlikely given all the noise they've made about it over the past 4 months).

Just last week, TSMC said their 28nm (planar) process only accounted for 5% of their revenues. It's still early in the 'commercial shipment stage' for 28nm products. For the evidence of commitment you're looking for, you need to give STM more time.

FD-SOI responds strongly to back-biasing techniques (both to increase I_on, and reduce I_off). As well, the effectiveness of back-biasing techniques are not diminished due to scaling effects in FD-SOI. In contrast, back-biasing on planar bulk processes are not very effective at sub-100nm gate lengths.

In regards to the broader FinFET vs. FD-SOI debate being discussed in this thread, I have no opinion to offer.
