Not sure why this would affect price at all. It's not like R3 would sell every token instantly.
Ripple regularly releases a billion coins into circulation. Just since the beginning of last September they released over 3 billion more coins. These US legal cases take years sometimes, so likely 10 billion or more will be released before the case is decided. Another 10 billion during the appeal.
If R3 wins the profit is just split between Ripple and R3. No difference. Remember Ripple has billions and billions more of these centralized tokens they plan on releasing anyhow.
So, unlike other coins, Ripple is not limited to supply? Can they produce coins as they want more and more? IN that case, the value should be 0. Otherwise, the creator of the coin is the real gainer, not us.
