Later this year means december VU? Or can we expect it sooner?
Designing an UI without taking direct player feedback on each UI element as you're designing it is a mistake if you ask me. A developer that doesn't play the game can't understand as good or get the feel as a normal player would for the UI elements.
If you launch the UI update (in as working condition for the UI that is currently "finished") as an alpha release you can get direct feedback from most players. It should be possible to switch in the client the old UI vs new current alpha one until the alpha one is finalized. This way you can take direct feedback as you make new UI and improvements.
Maybe semi-weekly or monthly updates to the alpha UI could be added where revisions are made based on player feedback, again players would be able to give more feedback as it is continued to be improved/expanded.
For example you have not shown us any UI elements regarding auction, trade terminal, repair terminal, society terminal etc. You're bound to receive a lot of player feedback from this after you launch the UI update. Isn't it better to take in suggestions and add an alpha UI in increments so you can take good feedback early on the development? A time saver and money saver if you ask me.
Like just look how many suggestions for improving society terminal here:

You have one of the most loyal and dedicated playerbase out there. Use them, they got years, many even decades of experience in EU and we all want to have a good experience in the new UI update.
