No you won't get any BCC from blockchain.info as they didn't give any statement about it.
Until they say something, it means they don't support the hard fork (i.e, they won't add it to their wallet).
They might be waiting.
Just use myceilum. It's better.
There is no private key on blockchain.info wallets, so he can't export or import private keys that never exist.
It used to have the option to export private keys. Did they remove that feature ? That would be so weird and why ? (I mean since they used to have it as an option before)
