Interview is a great find; it is 11 months since it was put on Youtube so we could be near an update. From the interview, given a year has passed, it sounds like EMC2 is near or 1 year away from having a model that will simulate a working machine that will say 'it should work' or 'it won't work.'

This has been a long wait for many here, what's another year. LOL!

So, correct me if I'm wrong, but reading the new patent, Polywell now: 1) does not need an electron-beam-injected potential well to operate, 2) requires a 2.5 meter radius core to generate just 90MW of fusion power even with D-T, and 3) has even less of a chance than before of burning aneutronic fuels with a decent fusion Q.

If memory serves me right the first two of those assumptions was based on the results from WB-8, the High beta cusp device and some simulations. Everything should have been further validated/investigated in the proof of principle reactor that didn't get funded till now.
Considering the lack of a broader scientific experimental database, even if the latest experimental run they made did indeed show a glimpse of a promising situation (especially when they was shooting at higher power), I would suggest you to consider the first 2 points with a grain of salt.
The third point was just the result of a numerical simulation, I would not consider it meaningful until there is some scientific data to support it.

By my recollection, the potential well was vital to the favorable energy distribution, ion vs electron, for aneutronic fuels. I also recall speculation that a well could be created without electron injection by differential leakage through the cusps. Of course then you need some other means of heating the plasma.
