Hi, three questions for you experts out there

i) Are we going to see a 4K Handycam with built in memory (64GB as model FDR-AX30 - here) available in the UK ?

ii) Can anyone explain when shooting in XAVC S 4K mode why we are limited to MPEG-4 Linear PCM 2ch audio and not able to make use of Dolby Digital 5.1ch which would be great for Home Cinema systems ?

iii) Supposedly it is possible to store recorded material in XAVC S 4K onto a computer using PlayMemories Home, a decent size hard drive required I know at approx. 2hrs footage / 64GB. Are there plans afoot to be able to burn this media onto the (hopefully) forthcoming high capacity optical discs that will (even more hopefully) be playable on the forthcoming 4K capability players ? - Big question

Happy hunting..... Oh, and many thankyou's in advance - Kudos available for accurate / best answers
