To import into TB from another client, you might want to check out this tutorial:
FAQ: Thunderbird - Migration
FWIW, the rumors of TB's demise have been around since 2006, if not longer. While Mozilla now is very different from Mozilla then (read: leadership (or lack thereof), $$$, etc.), I predict (read: hope) that either someone will pick it up to support it, or that it will find another way to live. I suspect that most long-time, loyal users would be happy to chip in a few $$ to keep it going. JMHO.
Cheers,
