As I explained in the Rainy May thread, quantity (or even quality!) doesn't matter to the Allies at this point; they simply don't use what they do have the way they should use it. If France had gotten 600 more tanks (albeit very good tanks for the time), they would still have pathetically parcelled them out to the millions-strong army (several to a division). These would still be swarmed by dozens of German tanks, as well as Stukas. A divebomber could easily knock out a Renault.
The only way for France to survive is either a spectacular German mistake (such as obliging France in fighting WWI all over again) or a 180 degree shift in French military thought.
