I'm in the camp that feels waiting an additional two months to receive knuckle controllers instead of the wand controller and having choice between thumbpad and stick is well worth it!!!!! I'm also super happy that Pimax isn't going to make backers of the full set wait longer to receive the HMD!!!!
You need to remember, at the beginning of the KickStarter for the 8K, Pimax was only offering wand controllers. During the kickstater campaign enough backers asked Pimax to change to Knuckle controllers which they agreed too. Two months... fine by me if we are receiving vastly improved controllers! Thank you Pimax!!!!!
