Exactly. Same here pretty much and I'm actually sort of expecting a new technique at this point. Not something over the top but something that'll play into the skills she already has. I can't wait to see her speak, and as I've said before, if she was given chakra by Naruto, I think we'll see this in a flashback.
She may not appear, and at this point, I'm okay with that. I just really hope the focus doesn't shift to Sasuke completely AGAIN.

LOL
If she does have something new, what would you personally want her to have?
I suggest to not keep about her getting a new technique too high. Yes, it's likely, but, still, it's unlikely also :/
I thought the same think if she was given chakra by Naruto. Like when she appears with a chakra cloak, the background will turn darker and then we'll see some panels of flashbacks XD
If she does have something new, most probably, a new technique that she has mastered and we'll see what is it or slug summoning. Otherwise, anything close to those two options.
Sakura secretly trained to master the byakugou. I'm calling it.
Since it's a forbidden technique she kept it a secret even from Tsunade since she would probably forbid her from using it. It's only until recently that she finally learned to use it properly, that's why we never saw her use it before in the story.
The byakugou is basically a last resort techinque so before this battle it didn't seem logical for Sakura to use it given that there where many ninjas doing battle as well. It's only now in the final stretch of the war when they need all the power they can offer to fight that she'll decide to use it.
Out of all the new techniques and ways to show Sakura surpassing Tsunade this is the most perfect one. It would be a testament of Sakura's abilities as a medic ninja. And it doesn't feel impossible given that Sakura is practically a prodigy in intellect and chakra control. Not even Shizune learned Tsunade's strength techniques and she's just as much Tsunade's apprentice as Sakura, so that's pretty telling on how far above Sakura is from any other medical ninja.
What can serve as a clue is that Tsunade introduced the byakugou as a rule for her students, hence anyone that can master it is allowed to be involved in the front lines. Tsunade didn't make herself out to be a unique exception, she made the technique to be an exception that any medic ninja can apply. Otherwise instead of introducing it as a rule she would've just mentioned as to why she was a special case given the nature of her technique, but we are left under the impression that this rule can possibly apply to anyone capable.
Also, right after she activates the technique Tsunade starts talking about how she's not just a medic ninja which she proceeds to prove by using her super strength on Madara. I would find it ridiculous that Kishi also made Sakura be not just a medical ninja and yet leaves her to be just that in the most important battle of the series.
Seems that her gaining a new technique is more possible now than ever. Sakura gaining a new technique, it will most probably be byakugou like you said XD
