Confirmed:
SBS1985C
(BN SP) 
(BN 69)
Still stuck on Sv 69 after about nearly 2 weeks replacing
1932E's timings. Today it's still on Sv 69 as well, along with the
perm 1926Z. And given that 1974J went to 358 to sub the also de-reg
1929R from the 1st day & it's still stuck on sv 358 till today,
I've reason to believe that 1985C is the allocated replacement for
1932E, cause it did Sv 69 the first day 1932E was officially de-reg
from the cameo lists & stuck on sv 69 since.
SBS8470A
(MIA after accident)
(AM SP)
If I'm not wrong, today is its 1st day back on the roads. Today
back on Sv 21 (its ex-perm), 1815hrs along Loyang Ave in direction
of St Michael's Term.
8470A was reflected as AM SP in Wiki for the past months, when
in fact, it was in the workshop after the accident. Not much change
though for the front, but all the rear lights are now the crystal
clear kind (white colour, only lights up in the different colours
when engaged, including the indicators, reverse lights & brake
lights). The OCBC card ad still remains even though it's expired
way long ago. Will have to confirm 8292Y's status again soon cause
8292Y still doesn't have a Sv 21 perm stix till now when it's
supposedly 8470A's replacement ..
SBS8603J
(BN 69) (BN SP)
Actually I have my doubts that this bus was perm Sv 69 in the first
place at all. But it's been running around for months on services
like 12, 358, 228, 293, 291, 15, 36 and more. Same situation with
8641Z, and all this while it didn't appear on Sv 69 at all yeah. So
this bus is out to SP. 8662M might be the replacement, but then the
number of WABs to non-WABs wouldn't tally the e-tt. So need to
check again if 8662M is 8603J's replacement.
SBS9566B
(BN 65)
(BN SP)
This is the only BN 65 bus that I didn't spot over the past few
weeks consistently. 9830M seems to have returned, while 9566B did
Sv 28 a couple of days ago for a few days. So for now, 9566B should
be the bus out of Sv 65, replacement is 3116G (with the MBS ad).
Any changes (if there are) I'll update again.
