I just got (several) letters in the mail indicating that all of my holds in FSTMX/FSIIX/FBIDX were going to be converted FSTVX/FSIVX/FSITX. FSTVX/FSIVX/FSITX have the same holdings, but lower expenses. Sweet!
It looks like they've lowered the minimums for all of these funds. FSTMX/FSIIX/FBIDX used to have $10,000 minimums, but have been dropped to $2,500. And IIRC, FSTVX/FSIVX/FSITX had $25,000 minimums and have been dropped to $10,000.
