Jetson Tx2 4GB module is expected to be <$200 and released in Q3 of 2019. It's expected to replace the TX1 in price but double the CUDA cores. It's pretty much a budget version of the current TX2 since Xavier started rolling out.
Hmm not too sure about using it in the industry and their over-promises. However, I did buy a TX2 to build my portfolio personally and it's been pretty fun so far. 256 CUDA cores is definitely not a lot to play with though.
