Are you meaning "[up to] 0.002W" and [up to] &c." else presumably you have already concluded that it will definitely put out "something"?
And are you presuming *all* fusion reactions, inclusive of beam-wall interactions, or just fast-fast reactions?
Your question appears to presume that it can achieve steady state (watts) - or will "power" be inferred by some calculation of pulsed behaviour if it has some pulsed behaviour?
Somewhere between answers 2 and 3. More to the point, I reckon they'll still be too busy figuring out unexpected problems to worry about or be saved by power scaling.

I fully agree. If there was a "something unexpected" category, I'd tick that. Might be positive, might be negative... but it won't be what they expected. My reason for saying that'; no plasma experiment has EVER resulted in what was expected!
I voted 0.2. Why? Because with everything that has been going wrong in my life in the last 9 months, I expect the worst. BUT, since I have to at least pretend to be keeping my optimism I went with the only half bad option.
I'd also vote somewhere between 2 and 3. I optimistically expect positive results, but not so spectacular that critics can't deride them as marginal.
I hope that WB-8 and WB-8.1 can lead on to WB-9. If no show-stoppers emerge, I think that answer 3 would be feasible for WB-9. I know a lot of people would like to jump from WB-8.1 to a 100MW plant, but I don't think it will happen that fast.
