Sadly, we may never again see more True Tears... or that's what I used to think anyway.
Then Okada surprised me by referencing True Tears in Hanasaku Iroha.

Clearly PA Works still has some fondness for True Tears, and Okada probably does as well.
So with this in mind, I was curious, what possible future for True Tears would everybody be most interested in? :
1) "
Noe Wins!" 2 to 4 episode OVA, retelling the latter half of True Tears through realizing the dreams of ShiNoe shippers.
2) True Tears: The Crying Continues! We do a brief time-skip, focusing on the continuing lives of the main cast. We see how ShinHiromi are doing in their romance, we see Noe try to come to grips with her brother Jun having the hots for her (one way or another

), we might see Noe find a new guy in her life (this is if Jun isn't it

), we could see more of the relationship between the great wingman and Totoum's tragically forgotten girl.
3) Carnival Phantasm, P.A. Works style! We see the casts of HSI, Angel Beats, True Tears, Another, and Canaan all interact with one another. I have a funny plot idea for this that I'll share if anybody is interested.
4) True Tears: The Next Generation! We do a 15 to 20 year time-skip, with Shin and Hiromi as parents, and their child as the main character. That main character then goes through a storyline similar to what Shin did.
5) Any different ideas of your own?
