Ha, we'll see. Ok, my prediction: Xtreme 5 will have all WD's functionality (which is essentially what's already in Xtreme 4 but improved since it was first released). Upgrade pricing will take into account whether you have WD or not.

This is a simple logical extrapolation based on Xara's history and what's already there. I bet 10 imaginary TG currency units I'm right.

I'll dig this thread out when it's released (I'd guess later this year) to collect my winnings.
