As many will know, the old Bletchley flyover has been under reconstruction for EWR over the last year, and the section
bridging the WCML was completed structurally over the early May bank holiday. The reconstructed bridge is now much wider
and is more of a covered way or box tunnel than a simple flyover. The WCML tracks are spanned by 103 pre-cast concrete
beams, of which 14 support the OLE below.

I passed under it for the first time since the line was re-opened yesterday, and took a few pictures:

Is the intention still to build a couple of platforms at Bletchley for the
Bicester-Bedford route, which will use the flyover, on the "siding" curve
pointed to in

slightly east of the double-track line from Bletchley station towards
Bedford?

Yes, just to the east of the new bridge. I'm not sure whether it'll be an
island platform or two side platforms — the much wider bridge would make
either possible.

I suppose if the platforms were far enough south, before the split between
the line to WCML north and the "siding line" towards Bedford, then it could
serve for Bicester/Aylesbury-Milton Keynes trains. I imagine that trains
from Oxford will go either to MK or to Bedford, but Aylesbury trains may
only go to MK, so Aylesbury to Bedford passengers would need to be able to
change at Bedford.

Are there still plans for the line from Aylesbury to Calvert to be ungraded
to passenger standard and trains to run towards Bletchley, or has this part
of the East-West route been put on hold?

It's been quietly put on hold: not officially dropped, but not mentioned
recently. I get the feeling it may have been deferred to a later stage of
EWR. Apart from deferring the cost, that may also be because that
single-track line will also be used by HS2 construction trains, and they
take priority. The HS2 Infrastructure Maintenance Depot will also be
accessed via that line.

I've come across this video of the construction of the new flyover:
