it's been mentioned a little, but there's the new T413 now:
https://aixun.com/product/t413-integrated-smart-soldering-station/i didn't look at it too closely because i sort of don't care. i have a T420D i'm happy with, and i'm guessing this is just another SMPS model plagued by the 'gnd issue'.
however, one thing caught my eye. there will be a new platform they call "225". not sure if this new "
T225" handle is included yet or if it comes later as a separate addon (supported by a fw update), but supposedly
it can use 4 different cart platforms: C470, C245, C210, and C115. oddly, it seems they will begin selling their own 'compatible' carts as C250, C150, C080, and C030, respectively, instead of using the aforementioned JBC model numbers. i wonder if they're starting to get paranoid, feeling legal heat somehow from JBC, or if this hints at possible incompatibility with genuine JBC carts down the line.
the T225 handle has some extra gimmicks. it looks like it has an accelerometer built in that gives more standby/wake options. there are also buttons on the actual handle itself for changing temp.
