They already have. Where do you think that 1920x1080/24P comes from?
The USA is the first country to massively deploy digital HDTV.
Whichever standard is broadly implemented first is likely to succeed.
The global economy has changed dramatically over the last ten years,
so we can expect considerably more re-use of technology than there
used to be.
Since as you say, ATSC HD is based on layered standards, the PAL-based
countries are free to re-use the image structure while chosing a
broadcast modulation scheme which is a better fit for the broadcast
model used in those countries.
As you say, HD is all about economics. HD has been taking off quickly
in the USA, but primarily for customers purchasing sets of 40 inches
and larger, and (until this year) more due to the popularity of DVD
than HD. Compelling content is critical, and luckily such content has
been available in the USA for over five years now.
