I am struggling with the 6 block limitation. I also found out that the stomp doesn't do so well as an audio interface if you are using native or other vsts (round trip latency is fairly high).
My guess is that they will sell tons of these initially but there will be universal pressure to increase the block limit.
Source audio managed to squeeze 2 dsp chips into their ventris reverb pedal. My guess is that a 2nd stomp pedal will be released in the future. This is the footprint that people want. It just needs more processing power.
