One thing I forgot to mention is the effect of a rising middle class in China (and India to a lesser extent). They are rapidly gaining shares in the global consumer market, and is likely to exceed the American middle class as the dominant consumer market in the world (I am in no way an expert on this and have zero experience of working with global markets, maybe
@leavingthecity can provide some input). However, I think they will have a big impact on the religious institutions and the way religion is structured.
You are right in saying there is a rise in Christianity in places like South Korea and this could have an effect, but again I don't see this as seeping through to education (something South Koreans value) and government.
Although the majority of the Chinese population have no religion (and the religion they do follow are less dogmatic like Buddhism/Hinduism/Protestant), the Chinese culture also involves a decent amount of tradition and orthodoxy. So the traditional nature of the culture will affect global consumerism (and hence global institutions and religious institutions), but in terms of secularism I think educated Chinese and Indian cultures value it (this is secularism and not religion in itself) and will want religion out of government.
However, on the other side, there is a rise of Muslims families and their consumerism (for e.g. the Halal industry is estimated to reach about $2 Trillion). The biggest worry, however, is the Saudi-backed Islamic banks (more prominently ISDB/IDB) making all sorts of investments in return of people supporting Islam and the Shariah. Most recently, the well-funded Muslim Brotherhood (allegedly financed by IDB) tried to change the constitution of Egypt to make it more "Islamic" and they got into power by promising all sorts of investments and money into their country. This is very worrying from a secular point of view, but it is important to remember that Saudi is heavily subsidised by the oil industry which can be very volatile.
