Well the original controller they promoted was innovative so it was worthy of a release. I was intending to buy one even though I may not have a Steambox. Now they have gone off tracks. Adding button is desperate and probably to reduce costs of not having a LCD and the driver chips.
I only had a quick read but it seems they are hashing out various controller combinations and maybe picking then. Just stick with the first one announced to public and stop this division and desperation.
