Yes that was out of line, I apologize.
There are many examples of a publisher getting too eager for their own good. 10 years ago publishers were a bit less gun shy than they are now. Even developers. The advent of the 24 hour news cycle created a dramatic shift in everything. Once again I look at how Blizz makes their announcements. They wouldn't dare announce anything if they weren't certain it would be released as they said it would. Shifting to a different developer, Molyneux can easily attest to that fact. Grand plans, grand promises... imagine if you didn't even release the game!
I've seen the videos and quite honestly they're not much better than wire frames and texture mapping. It provides something presentable, but not much more. As for your edit. Prototyping is always a part of development. You can't really tell if something will work unless you see it live. See how it works. See how it reacts. There's no way you can see that via paper. Ask any developer working on a new IP. I can guarantee you that someone had to convince someone else that it was a good idea.
