Over the weekend (10-22-17), Naigon did a livestream showing the updates made to his Spark 2 and Spark Color 2 boards for their R3 release. Since SF Hero Tier uses the Spark Color 2 board... I figured you all could do with a teaser of what's to come. Obviously I have no idea when SF will begin installing these versions into Hero sabers, since they likely have a large stock of the SC2-R2s in the shop.
Spark 2 updates include full 3-channel RGB support, and Saber Tracks now allows for the blade to be turned on using the color and blade effects from the last used font.
Spark Color 2 updates include Saber Tracks now allowing the blade to be turned on giving the blade effects and color sets of the last used font. You can also advance color sets with twist or twist+aux.
Updates to both boards include: Smoother blade effects with less audio artifacts; Linear Hum, Linear Action, and Alternating Clash have been ported from Igniter 2.
He also unveiled his version of a "pixel blade", the IntelliBlade.
