This section of the leaked bungie contract with activison should clear this up:
Licensor's studio/development personnel shall be exclusively dedicated to working on the Products
during the Development Term (the "Exclusive Period"); provided, however, subject to the further
restrictions set forth in Sections 8.4 and 8.5, Licensor shall have the right to utilize no more than
seven (7) employees (but excluding any Key Members) and no more than ten (10) contractors to work
on and operate Bungienet (unless any Product is in a state of Critical Risk, then the immediately
foregoing numbers shall be reduced to no more than three (3) employees and no more than three (3)
contractors), (ii) no more than the greater of five percent of Key Members and one (1) Key
Member, and no more than the greater of five percent of other empioyees and one (1) other
employee, to staff, fund and operate a prototype team for a future Licensor action-shooter interactive
entertainment software product tentativeiy known as "l\/larathon" ("iVlarathon"), no more than ten
percent of the Key Member resources and no more than ten percent of all other
employees after the achievement of at least Three Hundred Seventy Five Million Dollars ($375,000,000)
in cumulative Operating Income to continue to staff, fund and operate a prototype team for Marathon or
otherwise engage in work on other Licensor projects or business activities, (iv) no more than twenty five
percent of the Key Member resources and no more than twenty five percent of all other
Basically it says that employees can only work on destiny, marathon, and bungie.net. It makes no mention of aerospace, which leads me to believe it is dead.
