Now with the off-season in front of him, Kane will look at his options and decide which team would be the best fit next season. The Blackhawks are in a rebuilding phase and will be ushering a new era of players into the lineup. It's unlikely that Kane would want to return to that environment.
It's highly likely, that many teams will be lining up in July to speak and offer a contract to Mr. Kane as he still has plenty of game left in himself and would make an immediate impact on any roster.
