Putters with more forgiveness and stability like larger mallets typically provide superior distance control because they maintain consistent ball speed and roll even on mis-hits. Unless you’re exceptionally accurate with your contact point (repeatable impact in the center of the putterface) don’t fall overly in love with the more traditional head shapes.
However I’d say it’s unlikely that a new iteration of the Mini is coming any time soon. Modern fairway wood designs like TaylorMade’s M3 and M4 for example are so good and so long that former Mini players can simply find the right fit and most likely get the same or even better performance.
Since Mizuno irons were number one on Tour back in the 90’s anchored by Nick Faldo Tiger Woods and numerous others who appreciated the buttery forged feel of the MP-14 and MP-29 models purists have held the brand in exceptionally high esteem.
