Never launch before your value prop is clear. If your product is new and innovative you must pair it with affordability. If you have that even a buggy incomplete value prop will be preordered and otherwise welcomed. If your value prop is unclear you won't be able to efficiently edit and then re introduce much less price appropriately.
Futuristic/new services often get priced out of the customers minds because it seems expensive or not really that useful. You avoid this by following my suggestion.
