Why does Nvidia sandbag their cards when revealing a new generation?

[Heartbreaker]

Problem with that is EVGA only lets you trade up if it's within 90days. We won't see anything new in that time frame.

That seems like a reasonable time-frame. It's more to prevent getting blind sided. This is high technology, if something better comes out 3+ months after your purchase, that's to be expected.

I have seen a few people on Reddit, using this is to step up from RTX 2000 cards that they bought, and actually getting RTX 3080 or 3090's shipped already, so it worked out very well for them.

Though it does seem like a loser for EVGA. They giving $1000 credits for used RTX 2080Ti cards that they can't hope to sell anywhere near that.
