I don't think it's likely, the only hope I'm holding out is that as the device nears end-of-life Asus might grant the encryption keys to a trusted developer.
That's a long way off, and I expect to see development grind to a halt as devices with the .26 firmware become more scarce.
I'm really kicking myself for accepting the .30 upgrade - I think I saw the notice that NVflash didn't work on it two days later.
