In the thread "[London] transport related sights" the disscusion was
that the tube runs only to Terminals 1 to 3 at Heathrow and not to
Terminal 4 due to extension work.

This means that the only railbound PT serving T4 is "Heathrow
express" ?
T1 to 3 are serviced by Tube and H-Ex?


Yep.


As I will fly to London on wednesday (from Vienna), I'd like to know
my options! :-)

What's the difference in price, the ticket costs for H-EX seem to be
quite expensive. Don't they?


Hex is more expensive.
However, if you are arriving at T4, you can travel on Hex to T1-3 for
free, and chance to the Tube there, or their is substiute bus service
from T4 to Hatton Cross to pick up the Tube from there.
