The saying goes, "There's nothing new under the sun," and, truth be told, it isn't easy these days to find new areas of research concerning blackjack matters.
Still rather odd. I would have thought that, even if you disqualify online blackjack altogether which is a continent of unexplored theoretical ground, you would still have plenty room for discovery in the almost infinite conceptual area of shuffle analysis, or perhaps the myriad new blackjack variants being presented. I'm currently engaged in about analysis of seven or eight new developments in blackjack which can conceivably yield significant practical returns. Finding new areas of research is not the problem. Finding time to do it all is my problem.
Perhaps, if you replace "blackjack" with "traditional blackjack card counting" the sentence makes more sense.
