I'm sure there will eventually be a Chapter 6 since the game has a pretty loyal fanbase. But I don't think it'll be out for a while.

Chapter 6 has been confirmed, but no date given. Here is the cryptic message from TapBlaze:

My story simmers, not yet done,

In ovens of time, under the sun.

The pizzaiolo waits with care,

But this next slice isn't quite there.

A journey ahead, through crust and cheese,

Patience required, like a gentle breeze.

More than one trip around the sun,

Before Chapter 6 begins its run.

How long to wait until it's served,

This tale you've long deserved?

That’s great news! Do you think we should make a page for it on the wiki already or wait until there’s more information?

I will get one put together as a teaser for it, along with the construction blurb.

When was this message uploaded? Tbh, an over-a-year wait ain’t so bad. Here’s hoping for more seafood toppings, or egg.

Got posted to Discord a few day ago from Instagram I believe. I can find out for sure. More toppings, or a white sauce.
