Well, let's do some quick maths here:
- First season is around 6GB
- Episode 5 is said to be around 2GB
- Most people guess we'll get around 12-15 episodes in total
- If we take the lowest episode guess (12) with each remaining episode (5-12) being 2GB each:
- 8 episodes x 2GB per episode = 16GB + 6GB season 1 = 22GB
So, if DPC is estimating 25-40GB total then they're either overestimating the size or more likely it will be more than 12 episodes. The max 20 episodes they mentioned would make it (16x2)+6 = 38GB total, so we're probably in for something between 12 and 20.
