Think of Civ as the Goose that Lays the Golden Egg. If you own the Goose and depend upon it for your major source of income (Firaxis/Sid Meier) then you take very good care of it and make sure it has a long, prosperous life. You stretch out releases because that's how you earn your income. Flood the market with low quality stuff and the franchise suffers. So you have to tease the fans and take your time, but not so long between releases that people lose interest and wander off to other pastimes. It is a balancing act. You time your releases based on programming projections, to be sure, but you also plan your programming around income projections and plans for growth or diversification.
