Although mostly switched to HD5 ( black - still no cracked buttons after approx 3 mths!!) i still occasionally use the older flash based sony nw70d. Takes the small mem stick duo but limited to 128mg max. While browsing specs for Sonic Stage 3.2 noticed that one of new functions is "supports MemStick Pro now".(Which means large size sticks!) Anyone any ideas if that might mean can use larger duos in a NW70 ??? I would suspect not - presumably a "firmware(?) issue" with the 70D. Greatful for any confirmations? Thanks.
