These companies don't bank on making money from hardware sales anyway. The only console to be sold for a profit early in its lifecycle in years is the Wii. PS1, PS2, Xbox, 360, Gamecube, all sold at a loss early in their life. The money is made from liscencing software. Now, what Sony was losing initially from the PS3 was higher than any other console I can remember, maybe ever. But still, I think that cutting cost to even $50 below manufacturing would help sales in conjunction with the 2008 lineup.
I can't see a price cut coming in the next month or two. Summer is more likely. It might even be Fall before we see another price cut. It'd be great for Sony if they came through with one. Currently they are only $50 higher than the 360 and offer arguably a better value in terms of what is included.
