Games are going to take time. Sony can't do anything about that now. They could introduce a price cut now and sell the machine to those who would like what's available now and in the short-term future, even if not a big audience. What would be the negative effect of that?
Less money. Little momentum. Nothing to play it off.
I was skeptical of the price cut in the US as well, but then it was already more expensive and they appear to be using it to shift old stock and roll in the new. (And it's still under question if they'll handle it well, or if they'll lose momentum by going right back up to $600 for too long.) And $500 was already one of the INITIAL price points out here, they just tossed that SKU.
What's the incentive to bump things, say, 10% now, as opposed to bringing in more from the sales they DO get, and timing a price drop along with a real release? They're already getting a boost from the Minna no Golf bundle (in both 20 and 60GB varieties), but I don't think they're going to get real momentum until one of the big titles goes--certainly nothing to distract anyone from the Wii.
Later on, the momentum can be larger, the production cost less, and... well... you'll have more pistons firing at the same time. I'd rather shift into a higher gear faster than get a smaller gain and risk stalling.
Not to mention a "fairly-soon" price drop would kind of annoy the people who DO pick up the MnG bundle right now, unless they're going to start handing out rebates.
Technically, it might not have been bad to drop it somewhat along WITH the MnG bundle's announcement (and a lull in Wii releases), but since they didn't... (or at least "not by much"--there might have been some sway, I suppose) I can't see a global drop coming in the near vicinity. They can't wait for one of the main three franchises, since they're not apt to be out in time for the holidays, but I don't see them dropping yet.
Yes, they usually drop price during the summer. Not so much "within the first year." They're a bit off-kilter at the moment, and have to choose their timing well.
