while tis is not likely, tat might be the B7R demonstrator tat
SBST is trying out as a replacement for Mk II's. cos there are
rumours of a B7R demo in SBST HGDEP, jus tat i'm not sure wat
bodywork they are using or even worse, it may actually be a rumour
and the bus itself could be a private vehicle that is jus parked
there.
there is the possibility that the demo VSO, or heard it's named the
"Concept Bus", may come out soon. note that the difference is that
it has a rear desto slot for a VSO, though the back looks more like
a Trident.
the body could be
made by BA/HG (Bus Assembly/Hougang). there were rumours it may
re-open very soon due to the fact that new buses are coming our way
since there will be a bus retiring-and-purchasing wave from next
year all the way to 2009, when the Mk II's, Scanias, O.405's and Mk
III's retire. the first batch of Mk IV's will start retiring only
from 2012 onwards.
meanwhile, all the above are jus speculations, though i can confirm
with you that the bus is here with us, or more correctly, with
SBST. so hope no one will continue to say that it died or
whatsoever. 
now one last photo - the back. photos are courtesy of
