Are we still only getting the 600i Explorer variant in 3.2?

Yes. The Touring one is in production, but it's not going to be in 3.2.

We don't actually have the Touring module on a schedule yet, so it's a good time to invite people to check out the RSI roadmap available at robertspaceindustries.com/roadmap. When we have a better idea when the Touring module will be ready, you'll see that appear on the roadmap.
