From what I understand there probably won't be any 16 GB miniSD. Quite frankly, its a dead format, none of the card manufacturers are working on expanding it, instead concentrating on microSD and SD. I've actually read that the 16GB microSD should probably be announced around the same time that the 12GB is released, so I'd guess its probably coming end of summer. With SDHC's limit at 32GB, it seems like not long before we'll be at the limit for SDHC and microSDHC, and have another new format shoved down our throats. Then again, I'd definitely be happy with 'only' 32GB of space in my internet tablet or smartphone.
