Update: It appears that these are simply test sculpts by a new sculptor, back in 2008. So it is extremely unlikely they will get into production.
Tau Model Pics From Gamesday
These were sent to me and linked by several people that are getting excited for an upcoming Tau release. Now these pics were from Gamesday last fall, but I figured that since people are rediscovering them, they were worth posting up again. I think people are thinking that these might all be new models for an upcoming release, but I am very certain they are from Gamesday last year.
The site these are coming from is in Hungarian, so I cannot tell if they are proclaiming these as new or who actually took the pics. Anyhow, take a look at the other pics, but please remember that these are at least 6 months old.
