I’m considering buying a case of 0W-30 SS to have as backup. It would be over a years worth for my Jeep.

Yeah I think that forums don't have the same issues as "social media." I put them in a different category.
God forbid I try searching for information! What a novel concept! Someone should invent social media where a bunch of people can share their thoughts in an easily indexable, searchable manner!

All I see on forums and social media is that no one knows what the changes actually are, but many people are all hep/can't wait like kids at Christmas in anticipation of this unknown elixir or stocking up on the old formula in fear the new one won't be any good.
Speculate all we want, but we can hold Valvoline Restore and Protect in our hands and send off samples to various labs... and we consumers still don't know what's really in it.
My most recent shipment from a few days ago of SS 5W-30 is labeled API SP.
I was pleased to get this formulation as I was using it to supplement leftovers from a previous shipment.
I am curious if the current and upcoming formulations are compatible if blended together.

Can you post a photo? I don't think SS has ever had API approval. There are too many limits on the formulation, and AMSOIL formulates their best oil possible in the SS line, which they can't do under the API constraints.
I should have been more specific, my apologies.
"Use in applications that require any of the following specifications: API SP..."
It will most certainly be compatible with the new formulation. Will have a similar additive pack (obviously I don't have any real knowledge of the new formulation but one must assume it will be similar enough it could be mixed. I imagine it will be an iterative reformulation).
But that would be EVOLUTIONARY!
I’m running Valvoline Restore and Protect through at least November, so when the dust settles there I’ll consider buying more Amsoil then. Hopefully by then, the latest SS will have been released and who knows what the base stock percentages will be by then and if supply issues would affect them. 
I don’t see the point in buying far ahead for 1 vehicle. I do have the next oil change on hand to get me through this year if need be.

Welp, I caved 
and bought ahead for 2027 when I’m back running AMSOIL Signature Series. 
Whats going to happen; if anything, to the SS reformulation coming out soon, due to the forthcoming shortage ( if the formulation would need to adjust again due to base stock supply) and what (most importantly to me) the costs will be moving forward as well?
Therefore, I see no value in waiting until later this year to buy given the uncertainty.

The way I figure it, if it does come out I’ll just buy more.Welp, I caved
