New QNAP releases in 2021?

[Enquiries]

I'm considering the QNAP TVS-473e for a combination storage, surveillance, etc solution. I think it was released in 2017, but a lot has changed since then. Do you have an idea how long QNAP waits before refreshing a product? Do you foresee any new release from QNAP this year that would be a step up from the TVS-473.
I'm particularly interested in a 4-5 bay NAS. I have a 2-bay QNAP now and have some familiarity, so QNAP would be my first choice over other brands.

Qnap is about to release its new 73A series. This will be replacing the 73e series model. It comes with a slightly faster CPU and faster LAN ports as well as NVMe cache.If you do like the HDMI port you can add that via PCIe graphics card.Otherwise, the 73e series is still a good NAS and capable of doing anything you would need.I hope this helps.
