Well, that's a shame. While some of those mostly classic adventures are just OK, I think others deserve better and could really flourish with a longer treatment. The giant series in particular is so bare bones that it's really ripe for additional detail.
As more and more adventure anthologies come out, it'll be interesting to see if Yawning Portal starts to fade. I'm running an every other month Radiant Citadel campaign, and all of those adventures so far have been a lot of fun right out of the box.
I'm currently running a group through a "best of WotC 5E short adventures" campaign. This is what I have lined up for them:
Level 1 - The Joy of Extradimensional Spaces (Candlekeep Mysteries)
Level 2 - Scream of the Crop (Stranger Things: Welcome to the Hellfire Club)
Level 3 - Baker’s Doesn’t (Dragon Delves)
Level 4 - The Fiend of Hollow Mine (Journeys Through the Radiant Citadel)
Level 5 - Tockworth’s Clockworks (Keys from the Golden Vault)
Level 6 - Axe from the Grave (Keys from the Golden Vault)
Level 7 - Gold for Fools and Princes (Journeys Through the Radiant Citadel)
Level 8 - Heart of Ashes (Keys from the Golden Vault)
Level 9 - Tammeraut’s Fate (Ghosts of Saltmarsh) OR Affair on the Concordant Express (Keys from the Golden Vault)
Level 10 - Between Tangled Roots (Journeys Through the Radiant Citadel)
Level 11 - Shivering Death (Dragon Delves)
Level 12 - Dragons of the Sandstone City (Dragon Delves)
Depending on how we're feeling, we may or may not then go on to tackle some of the level 13-16 adventures from Radiant Citadel and Candlekeep Mysteries.
In selecting adventures, I did include the reprint anthologies (Tales from the Yawning Portal, Ghosts of Saltmarsh, and Quests from the Infinite Staircase) for consideration; it's pretty telling that only one adventure from all three of those books made the cut and even then I'm not 100% sure I'm running it. FWIW, nothing from the new Forgotten Realms: Adventures in Faerun book made the cut either.
Regarding that Silver box from B&G, long shot but if it is something from 5E's back catalogue I'd love them to do Tomb of Annihilation, which came out the year before B&G started but richly deserves a deluxe treatment.
FWIW though, I'm 90% sure that Silver box will be a new product. If it was just an older B&G set going back into print they'd just say so (they've announced another print run for their Keys from the Golden Vault DM Vault, for example).
