An Activision Senior Director working on Destiny has listed 'monetization modeling' as a current project on his LinkedIn profile.
The LinkedIn page belongs to Senior Director of Product Management for Activision, Ryan Wener.
While the term 'monetization modeling' is too vague to safely draw conclusions, Activision has recently introduced micro-transactions to Black Ops II. Meanwhile, the case for micro-transactions is frequently defended by industry spokespeople including Cliff Bleszinski and an EA executive.
A new batch of concept art for Destiny was released earlier this week.
