Is Peter Laird returning to Volume 4 simply to wrap it up?

So in other words, we get about a year or two more of Volume 4 when Laird returns simply to tie up all the story arcs he had going since 2001. It looks like Volume 4 might actually have an ending after all.

My question is, what happens after this? If Laird ends Volume 4, do the TMNT go into comic book hiatus yet again...or will Tales simply continue to go on as long as Mirage can afford it?
