Anyone care to speculate on how long it will take de-bug this aircraft?

Years!!!.

As does any modern military aircraft. Software updates are an incremental
process on today's platforms. And just when one box is finally stable and
meets requirements, it's obsolete and unsupportable so they rip it out and
insert a new one, with it's own set of deficiencies and bugs.
