The Heart guy season 2 will probably air sometime this year
Salvation season 2 aired on M-Net late last year, M-Net City sometime this year
Can't help with the rest
When is DStv going to air the next season of these shows? I'm certain it has been over a year since a new season was shown of the following.
Bosch, channel 117, last season shown season 3. Bosch has had season 4 aired and has been renewed overseas for seasons 5 & 6.
Bold Type, channel 116, last season shown season 1. Season 2 has now aired overseas, season 3 has no date but is in the works.
The Heart Guy, channel either 116 or the now defunct MNet Family, last season shown season 1, was supposed to be on 115 last year but was dropped at the last minute. Had season 2 and 3 shown overseas, unsure if there is a season 4.
Salvation channel 115, last season shown season 1. Had season 2 shown overseas was canned afterwards.
