Eth Node Requirement Update!

If I'm not mistaken Ethereum developers plan to adopt a POS model, allowing us to host nodes and get paid for doing so.
My question now is; How much Ethereum is required as collateral in order to become a staker/validator when Casper goes live?

Some says it was meant to be 1000 ETH, whereas I'm seeing Tweets circulating that it is only 32ETH now! Could a Ethereum Developer tell me the exact requirement? If it's 32 ETH, i'm not gonna miss this opportunity to buy Ether at bargain prices and become a Validator myself!
