While the DC V2 looks like a step backward (now Flex; wasn't V1 a DC-DC variant?), the ZS-A4S V3 looks tasty as hell. Esp. now it looks like 92mm fans are a go, rather than the hard to source 80mm. I can't work out from the listing when they're expecting to ship, though. Seriously tempted to give it a go, despite the current international shipping constraints.
