I think that those categories are somewhat questionable; lumping many varieties and strands into a single term ('Black English') and mixing regional variants with second language without distinguishing them is debatable categorisation. Also, while there will be changes in English as a result, I think that there is an unproven assumption that overemphasises their impact. Most native speakers of English quite simply don't have that much contact with, say, Chinglish, so where is the influence?
Japan has been the second-largest economy in the world, but its impact on English has largely been confined to adding a number of words to the vocabulary (tsunami, sushi, etc). The concept of a monolithic single standard has long been questioned or ignored, as seen in the acceptance of regional variants of usage, spelling, etc.
The impact of globalisation has been overestimated IMO- people can go to their supermarket and buy products from all over the world in complete silence, blissfully unaware of how people speak English on the other side of the world. People doing the trading will be affected and this might move into the wider speech community, but most consumers can carry on regardless.
