And even if you owned only a single share of Hasbro, you would have received a proxy vote. The only way the original rumor can be true now would be if the announcement is Company X has made an offer for the WotC IP and Hasbro has determined it is in the best interests of the shareholders to accept said offer pending approval of tha majority, at which time you'd receive your proxy.
That has happened before, but it would mean many many months before such an offer could even be formally accepted and even longer for such a sale to go through.
Given that, I very much doubt the veracity of the intiating rumor.
I now return you to your regularly scheduled speculation thread.
