We don't know the exact number of how much they've left, but running the numbers says 'not much'. We know for example,
how many employees CIG had over the years. Cross-reference that with the average salary of employees and that's a hundred million gone at least, even if CRoberts has been underpaying his devs and keeps them going with the promises of prestige and something good for the resume, they're running low event without adding celebrity, animation and studio costs. To make matters worse, their initial backup plans (SQ42 ship sales),
as confirmed by official sources, are failing, and there is still a lot of
features not yet implemented. And Chris Roberts is still being his overly ambitious self, unwilling to compromise on his vision to do everything. Calling this a critical overextension would be like calling the magazine explosion on the HMS Hood a minor malfunction.
Ostensibly, CIG is trying to appear more transparent now, reactions to this are divided between cynicism and Alpha Complex tier mandatory happiness. Personally, I think the attempt at transparency would be more credible if that rather optismistic progress log didn't look like it's full of people who had their faces stapled into a perma-smile.
