We already have mining GPUs and those are not used even by the miners due to very high prices in comparison with regular cards, not to mention their ridiculous warranty period of only few months and very limited resale value  

If they intend to go down that path again then no thanks.

Also in the EU there are strict laws that require that seller must give basic warranty of at least 12/24 months so this cards have been available only for short period of time.
