Yes, they are still available for sale in Italy when I write, in May 2019: just two days ago I shared with a friend one Moretti alla Toscana and one alla Piemontese.
Le Regionali can mainly be found in local family-run grocery stores or in supermarkets. These beers by Moretti (whose lager is anyway one of the most popular Italian beers in Italy) are not likeky to be found in pubs or restaurants instead. Those - mainly small - restaurants who offer local foodies and drinks in particular may have special beers by Moretti in bottle or from tap also.
Finally, I don't know much about distribution in the south of my country, since I live in northern Italy. Things (and most popular brands) may change significantly county by county but Le Regionali are all supposed to be distributed nationwide, not each one in the county inspiring it.
