Tau Titan?

So Chapterhouse, that treasure trove of shoulderpads and alternative Rhino bling, has offered up its first vehicle, and it's a doozy: The Tau SAW

I'm completely unsure what to make of this. I know little to nothing about Tau fluff apart from the "greater good" gestalt. Do superheavies even make sense for the Tau? And because of the Tau aesthetic, I think there'a a bit of an issue here with the model looking like a small vehicle merely enlarged. That's what happens with continuous lines...I feel like it needs more detailing. But then again, I haven't seen it in person.

I really love Chapterhouse, and I hope they continue trying audacious things like this. Good luck, guys!
