Ultimate Papercraft 3D is a promising new alternative to the de facto standard Pepakura Designer (PD), it pretty much has the same features but with some new stuff (outlined above). I encourage the designers to download the demo and try it out. It's free to try and $39.95 to buy.
Will it unseat Pepakura in its unfolding throne? only time will tell. Do remember that Pepakura has a 10 year head start - it was called Tenkai back then.
