Since I've only seen 3 more eps to be announced for Kaiji:
23 Heresy ( 邪道 / Judou ) 24m 12.03.2008
24 Conditions ( 条件 / Jouken ) 24m 19.03.2008
25 Investment ( 投入 / Tounyuu ) 24m 26.03.2008
26 Afterglow ( 残光 / Zankou )
I get the feeling that we won't get to see Kaiji vs Chairman and the series will end just like Akagi.
No, the first manga series has a proper ending.
It is separated into different parts, like Jojo. The last gamble is short.
