Thanks for your question and appreciate you're keen to use the dev preview build on your TA-1062. We've aligned the currently supported models with our software development teams, and I cant give a timeframe or firm commitment for TA-1062 at the moment I'm afraid.
Should the position change, we will of course post an update.
