It doesn't really seem so, or at least they seem no better or worse than what's been released already.
Trump supporters have been waiting months for the Wikileaks bombshell, October^H^H^H^H^H^H^H, errr.. November surprise, that will destroy Hillary and put her behind bars, implicating her in arms sales, pay for play access to the government, treason and if you follow the crazies, pedophile child trafficking and satanic cults.
Each time, the next batch is going to be the one with the damning information that brings her down, and each batch it's more of the same.
Sure, the contents don't speak well of Hillary, her team, or the media (and I think based on her actions she probably shouldn't be allowed near any sort of classified information again), but these are not the damning bombshells people have been fantasizing about, and those bombshells likely don't exist, because if they did, they would have been released well before millions of people had already voted, and not on the eve of the election.
