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.
The new TS2 features several design elements that contribute to making it significantly longer than the previous 917 D2 including an extremely thin titanium crown that’s approximately 20% thinner.
