JFC, new flying squirrel is NOT RELATED TO PACHIRISU. How many times are people going to speculate that every new pokemon revealed is somehow related to an older one. Remember the whole Munna/ Prevo Drowzee debate? Yeah, it was stupid. And so is this. Like others have mentioned, it's a different color and doesn't really look related at all (apart from the fact that, yes, the are both squirrels). A big part of pokemon evolution lines is existing features being exaggerated, getting bigger etc. NONE of that would apply if the new pokemon was related to Pachirisu.
