With a fierce competitor in town (BPS), it would only be natural for some employees to be nervous. It doesn't take much for a rumour to start, and once started it will spread like wildfire. I still consider the rumour to be baseless, but only time will tell. I'm sure this Christmas shopping season will be crucial, but I really think that it would be prudent to wait at least another year before making any hard decisions.
In brief, I'm sure Cabela's is safe for the short term, and likely even the medium term. Nobody can predict the long term however.
