A third reason is that the market analysis teams don't seem to be able to identify the true reasons for which a game is successful and what gamers really care about. They should be the ones to tell developers / producers to get them to see the reality of the game market. Yet, they keep bringing confusion into the developer community by feeding developers with unrealistic data and market trends. Solution: the developers / producers should really try to bypass these teams and get in close contact with the gamers in order to find out what they really want. The gamers are the ones who will buy your game if you avoid the cloning syndrome. If you don't respect that, then you will end up with your game boxes gathering dust on game shop shelves.
