Here is an interview with Brant Bridges, Sideshow Collectibles' Production Manager. There's loads of pix too.

Mention of future Lukes...
BB: Never say never. We really didn’t intend for this to be a complete ROTJ Luke, because there are a lot of possibilities with Endor. The helmet, the poncho, the speederbike, Wicket, ewok babies, handcuffs, and much more. He would need an entirely different head in order to fit the helmet, or perhaps two heads so that each would look ‘normal’ whether or not the helmet was on (read – no helmet hair). In any event, another version of Jedi Luke is a long way down the road. There are too many other characters to tackle!
Mention of "arm length" to be addressed...
RS: In hindsight, would you have liked to see anything changed?
BB: Of course, we’re always reviewing our products for ways we could have made the figure better, and we’re scanning the forums to see what the general consensus is. Perhaps we can tighten the hand connection, and I’m sure we can improve on the arm length for future ‘short’ figures. But all in all, we are very proud of Luke.
