You know what, I put Arkham Knight in my wishlist so I saw it changes because I check it daily. Day one was 40% and day two 50%. I have both screenshots to prove it. But... it could be just a one off.

Umm.. I see Batman Arkham Knight went down, discounted from 40% to 50% today (day two). So... maybe wait instead of “...no need to wait for a deep discounts.”? But I don’t know if it could go up again, hopefully always downward.
