I think SE sales expectations are unrealistic.
However, they are following the THQ failed example of focusing on 'out qualitying' (or out metacritic scoring) the competition with expensive AAA titles to 'knock' the competition out of the ring and get all the sales. This make or break mentality won't end up well for these types of games. Only so many can 'win' and the rest lose (are unprofitable and sometimes dangerously so).
But as long as they keep making Lara Croft games, I'm happy.
