You got to be kidding me Sony. According to my count, this is the sixth Sony Memory Stick version released: Memory Stick, Memory Stick Pro, Memory Stick Pro Duo, Memory Stick Pro M2, UMD, and now the Compact Vault. This isn t completely proprietary. It's just kind of silly. The Compact Vault is a variant of CompactFlash Type II, so in a way they are simply upgrading, but there is probably no chance in hell that it will be compatible with older CompactFlash devices. The initial release will offer 5GB of data and transfer at a nice 96.7Mbps. It should be popping up around the UK in November.
