Maybe I'm cynical but it strikes me as more of a marketing ploy to justify suddenly having to halve the cost of SXS media in response to Panasonic releasing cheaper P2 cards.

I understand the cynicism but the reason behind both Sony's and P2 E's cheaper price is due to the use of MLC NAND Flash which has a much lower number of write cycles than the expensive SLC flash. WIth the 32nm flash chips, MLC has about 10,000 write cycles whereas SLC has 100,000 - this explains the 1/10 life cycle. However, with the newer 25nm flash, the # of write cycles has decreased to ~8,000. This reduced write cycles is a major problem as the size of flash chips decreases. With the next size reduction (20 or 22nm), the # of write cycles will decrease again.
The only way to see significant reductions in the price of NAND chips is by size reduction. Thus, I do not expect a significant reduction in SxS prices in the next 5 years.
