How many years will it be until Pascal-like performance is available in a tablet form-factor?

Maybe never. Pascal is 16nm process and the mid-range gaming card, the 1070, uses up to 150 watts. A "powerful" mobile chipset uses a tiny fraction of that even at its highest settings. 100 watts for the CPU and another 150watts for the GPU is a staggering 250watts of continuous power no pocket-able lithium-ion battery can handle. If we want current gen graphics we're more than likely looking at a PC backpack solution. More than likely we'll probably be looking at some low watt solution, like the 35W AMD chipset in the Solus Q and accept a lower level of graphic quality, but still well above mobile standards. This may involve wearing a battery belt or battery hip-pouch for extended use. For lower run times the battery can be part of the headstrap with no need for anything to be pocketable.

  Part of me says just distribute the battery all around, thighs, legs, torso and you'll at least have good power. Another part of me says this is ludicrous, and is akin to strapping thermite and a bunch of loose strike anywhere matches into pouches all around your body.

    For many professional applications it is not hard to imagine people wearing some kind of vest or belt related to this.

Only by some combination of streaming and prediction; doing the rendering in the cloud, and using clever technology to hide latency.

Which Pascal? Assuming the smallest desktop Pascal, GP107 is at 768 CUDA cores. Tegra X2 Pascal has around 256 CUDA cores. They seem to be clocked similarly. The Tegra also has a lot lower memory bandwidth and stuff like that but we'll put that aside for now. We'll need the Tegra to x3 in performance. Maybe in 6? years we can get a GP107 performance in tablet form factor. The GTX 1080 has 2560 CUDA cores. That's another 3x from GP107. So maybe 12 years for ~1080 performance in tablets.
