Hi,
My answer is based on my experience with clients in this field. Nevertheless, seeing how this question is about the future, I wouldn't presume it to be 100% accurate.
In the near future (5 years): an increase in the amount of 'players' offering online courses and increased growth of the existing ones (in most subjects, except for those which are already saturated).
Later on (7-10 years): the closing of the smaller players and/or the buying out of smaller players by bigger ones (or companies not in that field but who provide complementary services).
Good luck
