Or so it seems.

Looks like it will be on the 19th April now instead and not on PPV.

From Boxing Scene:

According to Golden Boy Promotions CEO Richard Schaefer, the highly anticipated bout between champions Joe Calzaghe and Bernard Hopkins may switch from April 12 to April 19. The fight was slated for a April 12 date on HBO Pay-Per-View, but the plans appears to be heading in the direction of an April 19 date on regular HBO.

Schaefer told Dan Rafael that HBO is offering enough money, near $6 million, where the fight could be televised without the necessity of placing the fight on pay-per-view.

"I am working very hard to try to do the Hopkins fight live on HBO," Schaeffer said.
