Interesting! A JP machine is my next planned purchase, did notice some reviews mentioning that stampede is alqways the first mode. Will it just randomly select the first mode?

Yes, Chad confirmed that the first mode will be random - the idea was very popular as it is just a little annoying to always start on Stampede.

But the list of changes and updates is huge now, and I can't wait to get my hands on the update. Here's some of the latest updates -
