There has been some speculation in the past that Stratford Int'l might
never actually see any Eurostar trains stop there, and passengers would
be herded onto the Southeastern high-speed trains to get to either
Ebbsfleet or St. Pancras. I've pondered this in the past, but am now of
the attitude that they surely will stop there in the future - it's just
a question of when.

It's probably more a question of cost - in particular, the cost of
maintaining customs and security staff for international services.
