For the first few months they could not have sold any more than they did... maybe they could have produced 2 or 3 million more and be close to 22 or 25 millions by now? it would certainly be out of stock everywhere still...
There is a natural demand for the PS4, lowering the price would probably not yield much more demand, so Sony will keep it around 400$ as long as they can, at best you can expect bundles for the forseeable future (I hope they cut the price at next E3... but then, I have been wrong pretty often about that sort of thing.
