If the rumors are true and the unlimited 4g ends on Thursday, it might be a safe bet to call Verizon and cancel your tethering/mobile hotspot (if you don't plan on keeping it). Because my suspicion would be that at the end of the month they'll ask you if you want to renew it and you'll say no and only give you the option to choose from the new tiered plans versus the unlimited. Just my .02, I already called and got rid of mine.
