Now I know that there is some concern for Piko due to him not getting an update, and that there is uncertainty over wheather or not you can get a import code but I wanted to confirm that yes, you can still get a import code for Piko. (At least in 2019)
I have heard that since V2's permanent retire, you can get a import code from YAMAHA but that seems to no longer be the case.
You'll want to email any import requests to email@example.com
Something to note however, you may want to send the email and have its title in Japanese. I at first sent a bilingual email with a English title to no response. A week later I resent it completely in Japanese and I did get a response.
(Also, make sure to send your Piko serial code in the email)
However, if you want a actual update to the latest engine, I'd recommend reading Angel's blog post to have your dreams crushed.
And one last thing, please, DO NOT bother them by asking/begging for an update.
