I think it'll be rejected.

If the SEC is so intent on repeatedly postponing the result, I don't think they're confident in the stability of Bitcoin as an investment and therefore are unlikely to approve it.

There are so many other factors which will make Bitcoin a great investment, so maybe in the future they will accept it, but I don't think now will be the time.

I wouldn't say it's particularly necessary, since some wallets offer a lot of features anyway and are quite secure.  You could even just buy a hardware wallet like TREZOR which is nearly completely safe and would still take a lot less work than developing your own wallet, especially if you needed some of the features that major wallets have.

Seems to me that it doesn't matter that much.

I know anonymity is important to some people but this brings a lot of bad publicity to Bitcoin with the darknet and illegal activities, with things like Silk Road, and this won't necessarily be great for OpenBazaar.

Then again maybe publicity doesn't matter too much, since Bitcoin is a fairly anonymous service in itself.
