The OP asked two questions
I cited Valve being unable to give an accurate release date despite being regarded as one of the best developers on the PC. In fact don’t they have a phrase coined after them for the inability to meet deadlines? (rhetorical)
What is REALLY going on?
I stated, as have many many others, that SD is under contract with regards to Brink. If you want more information go hassle Bethesda.
Valve being better than SD is a strawman. This was never a point of contention and has ZERO bearing on this topic.
SD’s future plans and commitments are also largely irrelivant unless you want to tie them into 9/11 and fake moon landings. I think even the worst developer would be able to plan to complete DLC/patching and start work on a new project without a look of startled amazement that two obviously planned things would happen at the same time.
IMO people need to stop confusing their need to claw off their pound of virtual flesh with actual facts, as dull and reasonable as they may be.
