I may be wrong, but my feeling is that for the cases he releases himself under the Dan brand, it's self financed. He has to pay for the run, and the shipping to suppliers. Then obviously wait to be paid by the suppliers and also deal with any faulty returns etc.
I can excuse him in this sense only having the confidence for one container-load at a time, but I suspect that even Dan himself might admit in hindsight that not ordering another run of v1 given the time its taken to produce v2 was a mistake. Will he do more this time? Only Dan knows that one and I suspect that demand for v2 when its on sale will inform that decision.
As for pricing, I'd expect a considerable bump. Production and international shipping costs have risen a lot in this time, just accounting for inflation would add over £50 on its own. I'd expect over £300, with £349 being my rough guess but it could hit higher
