Wow, what a nice time, i still miss those times in when everybody was able to buy a whole bitcoin, but i remember the real fight that some users where having in there in the BTC/USD discussion on this forum.
They are not going to accept it as an ETF, it is impossible, because USA is doing as much as they can in order to regulate bitcoin.
An ETF I believe is inevitable. The primary reason why the SEC blocked ETFs is because bitcoins were unregulated. When the CTFC has allowed bitcoin futures, the SEC can not use that line of argument to block ETFs any more. You can have ETFs based on Bitcoin Futures, which are a regulated underlying. It will take time, but ETFs will get here.
