we had 8 patches in almost 2 years (21 months) since i dont see it releasing any sooner than a year from now (2Q 23) there is no way we only get 1 patch.
Well...
1 - We had three patches in the first two months and then one every four-five months since then.
2 - I think you are wrong both in your estimation of when it will release than with the number of patches, but time will tell?
