I doubt Remington will do anything until the Freedom Group is sold.
Remington has threatened to pull out of NY previously to do with restrictive laws that would result in losses of the Remington workforce and profits as with now. So the threats to move are definitely economic-based.
That a decision has been made is apparently just a rumor. Such a decision would be major news and does not currently show up today on CNBC or in any Google search.
