Current research indicates lifelong immunity to sars-Cov-2 after natural infection as the b and tcell antibody mechanisms move into the bone marrow and just keep pumping away.
And people naturally infected with SARS-COV-1, from the SARS outbreak, are still showing immunity to that virus (close to 20 years later). COV-2 is extremely closely related to COV-1 and it would be logical to extrapolate that the immunity lengths are going to be similar. At least more logical than looking at the cold virus immunity and extrapolating from that.

Correct on all accounts.
