Nathan Drake and Solid Snake Confirmed for PlayStation All-Stars?

The voice actor Eric Ladin who played Cole in Infamous 2 earlier reported he was back at work in motion capture suits playing Cole but not for Infamous 3. So at that point everyone assumed that he was playing Cole in the new PlayStation All-Stars Battle Royale. Now Ladin may have just outed two more characters through twitter Nathan Drake and Solid Snake. As you can see in the tweet above he points out he is working with Nolan North and David B Hayter who are the voice actors for Nathan Drake and Solid Snake respectively. However, this story was originally posted by IGN earlier today and I can't post a link to the actual tweet, because it has been pulled down. However, I can post you to a link on IMDB where both actors are listed as playing Nathan Drake and Solid Snake in the game. Even though this isn't a confirmed rumor there is almost 99% chance it is true. Why else pull down the tweet if it wasn't true? Unless Ladin is just trolling everyone and Sony has no intention of including one of those characters in the game. Sony is most likely waiting until E3 to announce the majority of the cast for the game so they didn't want any of the character reveals spoiled. So even though this is just a rumor right now I would assume that it is true until proven false; chances are Nathan Drake and Solid Snake will be included in the PlayStation All-Stars Battle Royale. What are some of the other characters you would like to see in PlayStation All-Stars Battle Royale other than Nathan Drake and Solid Snake?
