I haven’t heard of the exact release date but you may want to check on the following site for more details: https://www-ssl.intel.com/content/www/us/en/nuc/nuc-kit-nuc5i7ryh.html
I hope this helps,
I have seen that already, but it is not the right model.
Currently we have the following :
The H & K models have the soldered down wifi chip, the MYHE models have a slot to add your own wifi card.
I'm looking for the i7 version of the MYHE, which going on the above convention, would make the model number NUC5i7MYHE.
