The LA2P have existed in hardware for 4 months. Given the many reviews and the launch, seems a month+ was spent in beta and in marketing preparation for the launch. Beta is good for consumers, a more polished end product.
So I’d expect their successor to be already prototyped.
The LA2P uses from the public information a fairly low end internal hardware, higher end ones do exist, but at a cost. If you didn’t own anything, I’d say go for the LA2P using one of the past/present/future discounts as they are a good value for money. But as you own the LA2, I’d suggest just wait, get more months of use from what you own and let the LA2P successor put more of a distance (performance, features) from your LA2 investment. The higher end hardware can improve ambient and ANC performance, add multipoint, at a cost, so I’d suggest that future product be released, reviewed, and then probably it’s been nearer a year since your last spend and a wider gap in performance and features.
There’s features in Bluetooth 5.2 related to performance in true wireless, yet to be used by Soundcore.
I have no inside information, don’t ask for dates, but my best guess is on a 2-a-year release schedule the successor to begin to be hinted at in 2 months and released 3+ month from now. Some features had to be prototyped and tested in the software (Soundcore app) they don’t need to repeat, so the LA2P successor I don’t expect to be 6 months out, less, say 3-4 months out.
