I'm very confident that it will be a free upgrade to everyone who purchased the original cut.

Cela me semble plus que certain ou alors il y a un problème ! 😕It seems to me more than certain or there is a problem! 😕

Does raise another question for those who purchased the short version - do they have to pay again for the longer version?

I hope not. That would be the last straw (as we say here in Quebec).

J'espère que non. Ce serait la goutte qui ferait déborder le vase, (Comme on dit ici au Québec).

the last straw (as we say here in Quebec)

I think we know this straw in the UK too, often associated with a camel and its broken back.
Sort of wish I had not mentioned it now - so obvious the answer really.
The file will eventually be replaced by the new and if you bought the short, you would then have access to the long and no more credits needed.
