I doubt it will be any time soon. Ruger is facing at least one lawsuit with potentially huge financial consequences. Add to that that folks in an increasing number of States are discovering that the Mini is still legal. That will change in the future, I believe, but for now, the Mini is still available to them.
Some members here have managed to find gently used (not abused) Minis discarded by former owners usually because the former owners did not know how to remedy some of the flaws in their particular Mini. It becomes a safe queen, and eventually gets traded-in or sold off. After a little tweaking, such rifles often work very well.
A lot about whether or not this approach is practical depends on whether or not Ruger still offers parts support for your Mini. No expert, but it may be that some model-specific parts for older rifles might be in scant/zero supply, but other parts common to a wide range of models (such as springs/extractor/ejector) might be readily available.
A potentially serious problem that can be encountered on Minis is wear/damage to the rifling at the muzzle caused by improper cleaning/tools. In many cases this can be remedied by a simple re-crowning of the muzzle, which can often be a DIY project with the right tools. Even a more extensively damaged muzzle can often be counterbored, but this will be a job for a gunsmith with a lathe. Still a lot cheaper than a new barrel, and if done right, should restore the accuracy of the barrel.
In your case, and if you have not already done so, I suggest obtaining a "sufficient" number of reliable magazines (before they are banned in your locale), a decent stock of spare parts (including "fitted" spare parts, ammo which shoots well in your rifle, and any accessories that you wish. There may be a few tweaks you can make to your existing Mini that might be useful.
Best wishes!
