Dead Aim happens in 2002, so no it isn't proof that Umbrella crumbled during that couple month period. Really, there isn't proof that Umbrella crumbled at all. All that research and government subsidized laboraties dont just disapear because their company front stocks plumeted. But then again, I am thinking in real world terms, not Capcom world terms.
What plotholes did Outbreak create that didn't already exist? And I agree on the apprehension... I am afraid they will try to say 1967 was the date the Progenitor was discovered depsite all in game files pointing to otherwise.I believe UC will somehow be both a blessing and a cursing. It will answer lot's of questions that have remained unanswered, but I have a feeling it will add more plotholes, much like OutBreak did.
