Well, better Romeo and Juliet than Hamlet. SPOILER: Everybody dies.
If it does that, then it is kind of sad but I can also see why.
On the first point, it would be sad to see it end so soon because it could certainly go on longer, or at least could have if perhaps things has been paced out a bit differently. It does seem like things are coming to a head very quickly right now with relationship being narrowed down and such, and you have to wonder if this always was DPC's plan, or if they're purposely rushing it.
This is where we get to the second point, because when looking ahead the average pace of each episode's development, DPC is staring down the barrel of about 3-5 more years if they were to do 12, 16, or 20 episodes, and that is a lot of time for one game, especially given how hard they work on it. So perhaps DPC realises this and doesn't want to spend that long on it, so they've condensed their plans in order to finish in just 10 episodes. Somewhat telling was how they said they hadn't decided yet on the "scope" of Ep 7 which says to me that they are trying to figure out how to squeeze into the episode which might suggest they are trying to condense this into just 10 episodes.
I honestly hope it's not the case that they're doing this as at least 12 episode for 3 equally amounts of episodes per season would be more than enough and it would be a shame to rush to the finish line just because they don't want to spend so long on it.
You have to play music for them in order to get them to talk which means, before talking to the lowlifes, don't trade the guitar for a sword at the Blacksmith's and talk to Maya at the fruit stand because she'll tell you they like music.
