I personally think the following will happen in April '08, a few weeks before the release of GTAIV, so that it can compete with the X360's likely price cut.
US-I don't expect much of a price drop here due to the poor currency value lately.
80Gb $500->$450
40Gb $400->$350
EU-I expect high price cuts here and to introduce an SKU with the highly demanded BC.
40Gb £300/€400($600)->£250/€325($500)
Introduction of 80Gb SKU at £300/€400
JP- I don't know pricing her, but i think it will have similar cuts to th US, and introduce an SKU with the highly demanded BC.
Introduction of 80Gb SKU
What are you predictions on the PS3 pricing and SKU strategies?
