If everybody buys games just because their cheap and not because their good,then yes that decreases value.
How? The value to the consumer is the same but the opportunity cost of buying is greatly decreased. Conversely the cost for the publisher to produce another unit is zero.
The supply curve is therefore a horizontal line and since games are a luxury we can assume that their demand is highly elastic. So the Supply/Demand curves look like this.

Say at $60 they sell 100,000 units.
If they do that wait till they've sold 100,000 units and then drop the price by about half, then on my rough graph:

It appears they sell another 100,000 units. So by doing that they make 9 million dollars instead of 6 million dollars.
Now like you've said this may change consumer expectation so the demand curve may change a little bit.

Now it looks as if the only sell 66,000 units at $60 but they also sell 120,000 units at $30 so they still make 7,560,000 dollars
If you increase the number of steps down so say we start at $60 drop to 55, then 45, 30, 20 you make even more money.
As long as the amount that Steam recieves and the amount that the devs receive is always proportional I don't see the problem.

Also everybody waiting is not good for the dev´s who need money the moment their done with a game and not 5 months down the line.
Well that really depends on the contract that the developer has with their publisher.
