Sounds like some ego boosting yourself
Having known more then my share of authors/designers in the industry, I agree that there are some large egos there but there are also some fragile ones too. When I was a chat room host for WotC there was some authors and designers that refused to come in to the chat room for discussions unless there was a host there to make sure nothing untoward was said and or done.
Having said all of this. I am still not sure I am all for 5th edition and the place it is going too. I think that they are digging a hole for themselves because it is fast becoming an edition that will backwards compatible for all editions and thus the "last" one that could be made then. That is usually the consensus of most peoples way of thinking from what I am reading so far.
