Measuring such high temperatures is not simple, and a number of assumptions are involved, probably including the radius of the tungsten wires. Given that their machine is operating outside of its expected range, it seems more likely that they'll find a measurement or calibration problem rather than new physics.
I don't think it is more likely now. It is still possible of course, but reading

The results, recorded by spectrometers and confirmed by computer models created by John Apruzese and colleagues at Naval Research Laboratory, have held up over 14 months of additional tests.

Haines theorized that the rapid conversion of magnetic energy to a very high ion plasma temperature was achieved by unexpected instabilities at the point of ordinary stagnation: that is, the point at which ions and electrons should have been unable to travel further. The plasma should have collapsed, its internal energy radiated away. But for approximately 10 nanoseconds, some unknown energy was still pushing back against the magnetic field.
If there was such an error, I'd have thought they'd have caught by now. I'm more inclined to think something previously unknown is going on, even if it isn't a miracle solution to all our problems
