Nooooooooo Why change the UI? I mean, I like Thunderbird exactly since it's the only email client that didn't go into the direction of emulating GMail or Apple Mail or other mail interfaces that shows you the messages in a conversational manner. I like Thunderbird because it has more or less the same user experience of the old "Outlook" Windows application. Why change something that works??? At least I hope they will give users the possibility to remain with the classical interface, otherwise I think I will still remain on older versions (after all IMAP is relatively stable so I shouldn't have that much issues). The only thing I would like on Thunderbird is sync of the settings with a Mozilla account like Firefox does. Not that it's a big deal, I just copy around the profile directory (because reconfiguring 10 email accounts each time I change/format the PC takes almost 1 hour).
