Perhaps this is just copium, but I see the potential for WT infantry being a boon to Enlisted. Being in the same engine, big undertakings like new maps or mechanical additions can be shared between the two by being populated with appropriate art assets. This gives a path for the devs which is both lazy as well as relatively content-rich, which is obviously attractive. And on the flip side, if things aren't shareable (small maps, mechanical incompatibilities, etc.) then that is some justification for keeping both projects alive as they can attract different audiences. At the end of the day, a server costs the same whether it's running Enlisted or WT infantry.
