You betcha.

Telltale Games has really dialled down its WiiWare support in recent times: last October we revealed Back to the Future was not coming to Wii and now Puzzle Agent: Nelson Tethers is the latest casualty.

Cubed3 contacted Telltale, whose community manager Alan Johnson had this to say:

We're always looking to get our titles on as many platforms as we can, but currently have no plans for a Puzzle Agent release on the Wii.

With the studio's Jurassic Park series not heading to Wii either, it looks like we might have seen the last of Telltale Games on Wii.
