It's possible for them to release a HBM desktop card, it's also highly improbable that they will unless it gives them some type of edge versus nvidia's answer to 6800xt's value/performance and 6900xt's price point vs 3090.

It's also highly probable they already tested that config and it did not net them the gains they needed or wanted and or effected there bottom line as far as what they make per card vs the performance.
