When is the ETA of shipment for this?

For anything pre-sale or IC stage: I don't know.

For anything in the group buy phase: Usually such info is listed on the product page or GB page.

For anything in-stock: Usually such info is listed on the product page or GB page.

 

For anything already sold: Please check the project status page on the website. ETAs may change as production progresses or as global situation changes.
