Cry much OP? There is a lot to gain by announcing early. Investor interest, share holder understanding on R&D investment directly tied to a product, mindshare in the market with a slow burn marketing campaign, project interest from outside talent who will want to work with you (best possible type of recruiting) plus the internal cultural benefits to a project that isn't under lock and key from the public. There are many draw backs too, some you pointed out, but all you did in your OP is come off like a little crying brat who cant be patient for something. Hell the best example of this is FF7R, with the development crew feeling down after the first year due to project hardships, but being invigorated due to the insane support coming from the public. I remember one youtuber posting his story about the team being almost in tears from the outpouring of support and amazing fan response, and how much it inspired them to continue and make the best possible product. Sure some of that is PR spin, but I know how having people be excited over what you are doing is the fuel of the gods when you are feeling down. If you are excited about a product and its taking a long time, why not try putting some of that passionate anger you have there into a message to that development staff showing your support for the long hours they are working to get something out.
