I was joking.
It's good indeed to have development updates of a pre-paid product, it helps other to make the decision to pre-buy it and this helps trust.
But honestly I don't care a lot about development updates, I prefer to discover the whole thing when I put my hands on it. Moreover the development is so slow that even highly frequent updates can't suppress the hype torture.
But, what is more important for me would be development updates about post-released product fixing. The todo list gets bigger everyday.
