Here in England I simply wouldn't believe a number that high, seems pretty encouraging even for the continent with lower language barriers. But that interpretation doesn't fit the tale Andrew wants to spin.
The reality is my wanting to watch Irish sport in England isn't helping Hollywood sell anything, it's helping keeping my local Irish bar funded though - they've jumped the hurdles to get it so I don't have to bother fighting geolocking.
The US has already flooded the whole of the EU with their 'product', they stand to be hurt just as much (or little) an locals.
Would be nice if the EU sorted out the inequalities that allow differential pricing to succeed *before* full scale harmonisation but that's never likely to happen so market forces will have to do the job.
