Will diamond card prices go up once game comes out?

Wondering if I should buy 1 now? Or will more people opening packs put more in the market place? Thanks

In my opinion, I think they hold steady until there is a headliner or something that everyone wants. Then they may dip a bit. If anything they may go up a bit. More packs are opened in the first week (on a massive scale), than any other time of year.

Wondering the same. I packed Bellinger and Cole.

Likely go up because of the demand from new players. Yes there will be more packed but that's not meeting the demand.

I think many will stay steady but I could see Belly, Cole, DeGrom, Max, Trout, and maybe Betts going up by about 10%

How about the prerelease players Rivera/Maddux/Mantle/Sheffield/Glavine/Papi/Smoltz?
