Agreed. The main plot for season 2 will be based on the 4th novel as well as its most likely that the producers will be adding side plots/short stories from the other novels in order to add more content as well.
If the producers do add the extra content, I'm sure that the small stories from the other novels combining with the content of the 4th novel will make up for 14 episodes. Sorry if i go too far but if the producers still have more content remaining, Its possible that a few OVA's might be released after season 2 is complete but then again those are my assumptions for the Haruhi series. |
