So after FTX announced their card, Kucoin decided to go down the same road.
It is unlikely that the development of the card could have been carried out even earlier, and Binance became the pioneer among exchange cards, if I am not mistaken, other exchanges also began to follow this trend. Most likely, FTX just released this product earlier, and Kucoin is still testing it.
where you maybe able to find any info about fees and withdrawal limits?
There is little information. It is known that no money will be taken for issuing a card, and it will also be free in terms of annual maintenance. Withdrawal limits and commissions for purchases will be announced, most likely when it is officially launched.
