I have no idea what the tax implications are to the EU residents. The buddies I have that are based in Europe have not indicated that they will bid back to HKG, actually most of the bases in Europe on the passenger fleet are reportedly full with the exception of MAN due to the Dragonair Cargo offer.
I have not heard of any new cities in Europe or any increased frequencies to existing cities, aside from seasonal changes. There are two new cities planned for the cargo side (Houston and Miami) as well as increased frequencies to many cities in the US, and some rumored new passenger cities.
