The next wave of info is coming on October 4, 2016. The source kindly provides times for a few time zones:
– 6 AM PT – 9 AM ET – 2 AM in the UK – 3 AM in Europe
Of course, it's possible that no new Pokemon will be announced, but you can still look forward to the announcement of some new features etc.
Hope I helped. :) Source: http://nintendoeverything.com/next-pokemon-sunmoon-update-set-for-october-4/
