I'm not sure if it's already been mentioned in these 33 pages of posts (sorry I was lazy and didn't read it through) but wouldn't the most secure wallet on creation be the one that's put on a USB stick (encrypted or not) then shoved in a bank safe deposit box.
Nothing beats physical security offered by the brick & mortar people that have been securely holding stuff for decades.

It's a lot harder to break AES than it is to break into a bank vault.
Like I said "encrypted or not". Just because there's AES encryption on something doesn't make it secure though. Think about it, if someone holds a gun to your head and tells you to disclose your AES password to unlock your wallet, would you die protecting it?
If it's in a bank vault presumably that person would either need more leverage (like kidnapping a family member) and serious balls to keep you motivated since you're going into the bank alone.
Of course, there's lots of if's, buts and maybe's around all the scenarios but I was mainly trying to point out that physical security is one of the most important elements of security. Encryption is very helpful (and is another element of an overall security approach) but not the be-all and end-all of making a '100% secure wallet'.
Just my 2c,

I haven't read through all the posts either, but couldn't you use a
TrueCrypt encrypted image with both an outer volume and a hidden inner volume? The outer volume would have a small "disposable" wallet(s), while the inner volume would have your super-secret horde of thousands of BTCs. If somebody threatens you, you provide them with the passphrase for the Outer Volume where they can steal your "disposable" wallet.
