I hope it will be budism and not islam
Why? You don't want to pray 5 times a day towards the Mecca?
If anything, they are far more religious than many religions today. Catholics? Numbers are hyper-inflated (because in many country the State pays them money for every registered catholic), and many just stick to baptism and funerals, not even bothering with Sunday mass, oh and occasionally marriage because its fashionable...
The rest of the Christians are a mixed bag, some devote, some only appearances.
I still have to find out why Muhammad wanted people to pray towards the city he was born (i know, a revelation, but still...), or why they were praying towards Jerusalem before that. But in any case, this made them get good with maps, so they could build the mosques pointing properly. See? Civilization!
