IMHO, I wouldn't worry. There's not much you can reasonably do at this point if they're not vigorous to get out on their own.
My wife heard about it a couple days ago since Bass Pro is about 10 blocks from where she works and Cabela's is on her way home, lots of people she knows either frequent them or work there.
Cabela's has been losing market share for a few years and has been trying to sell for some time. One report says it's 5.5 Billion.
That will double the stores but there will probably be stores of both chains closed if they compete locally.

I always thought Cabela's was more hunting oriented and Bass Pro was more fishing oriented though they really thoroughly overlap.
Bass Pro is headquartered right here in Springfield, MO. Their flagship store there is amazing. Cabela's is in Nebraska and Bass Pro says they're going to keep their operations there.
