We are still far away from the solution. Estimates for the size of the completed tablebase are around 10 Petabytes. Compare that to the 140 Terabyte hard drive (later trimmed down to 18TB in the syzygy table) and we are still not anywhere near achieving it.
I don’t think that it couldn’t be done this year however, my gut tells me that it’s more due to a lack of trying. Supercomputers are rarely used for chess anymore and someone would have to convince probably a billionaire to “waste” millions of dollars worth of super computing time to achieve it. Once the tablebase is finished, how does one profit off it. Will they even get their money back?
The most interesting find to me at the moment is this world record 8 piece 584 move forced checkmate. It was found by Marc Bourzutschky last year in as far as I can tell the most recent attempt at the 8 piece tablebase. It contains 2 white dark square bishops.
