Back to the main topic. Does MODX have a future. I think it more for personal point of view. In small country like in Finland, almost all major digi/web-companies have adobted one of these monsters: WP, Drupal & (Ugly little cross eyed monster) Joomla.
In CMS business, almost all open job positions reguires WP or Drupal knowledge. That is one and only reason why i consider to "abandon" MODX and start to learn Drupal or WP. I know it's kind of stupid, but you have to think what brings bread to the table.
I like MODX. Haven't truely tried any other system to be honest
Story would be different if working as freelancer or in personal projects, but as an job seeker in the open job market, MODX is not "careerwise" move. So if you want to get hired (In Finland), don't bet on MODX or other CMS, which falls into this 1% category.
Also if MODX could show any growth in Market share, but it doesn't to seem growing any bigger?

I've been also pondering, why MODX is not growing even if it's getting good reviews
