Each season consists of 22 episodes, except for the last season which is 4 episodes longer, so the last season has 22 + 4 = 26 episodes.
There were 9 seasons before the announcement, so there will be a total of 9 + 1 = 10 seasons in total.
Each episode is 0.5 hours long, so to watch all the episodes in one season, it would take 22 * 0.5 = 11 hours.
However, the last season is longer, so it would take 26 * 0.5 = 13 hours to watch all the episodes in the last season.
To calculate the total time to watch all the episodes, we add the time for each season: 11 hours * 9 seasons + 13 hours = 99 hours + 13 hours = 112 hours.
So, it would take 112 hours to watch all the episodes after the last season finishes.
#### 112
The answer is: 112
