I think it's more that the broadcasters don't want to devote the
manpower to producing content in what they perceive (not entirely
unjustly) as an obsolescent format.  

Technologically speaking I imagine it would be possible to produce a
reasonable facsimile of a teletext display using MHEG if the content was
there, but once the analogue signal is switched off (and hence there are
no "legacy" teletext receivers to worry about), the people generating
the content presumably won't want to be constrained by the 40x24 format
anymore.
