If you look at this as a one-shot game, sure, but it's not. If everyone votes no the buyout would be rejected and the prospective buyers would have to offer a higher price to get it approved.

The tricky thing is that shareholder voters exhibit very weird and irrational behavior (due to proxies, lobbying, the T Rowe Price craziness, etc.), so I'm not sure game theory is terribly useful to begin with here.
