There will be a KyroII se, Hercules will probably be making boards with that chip. For Kyro3, we have to wait and see if someone buys STM to continue the research on that chip... so I wouldn't wait for that to upgrade my graphic card. By the way, make sure the games you want to play are supported by the KyroII before buying it. I am aware that some games, like Grand Prix 3, F1-2001... don't work witha Kyro based card. So do your homework before buying one of those cheap, great performing cards.
Hope it helps
