According to the Twitch broadcast schedule for E3, there are two games from Sony that they can't reveal but will be streamed. One game is a cross-gen PS4/PS3 game and another is a digital PS4/PSVita game. Both will happen on Wednesday. They will also stream Driveclub, The Order, H1Z1, Hohokum, Helldivers, and Planetside 2 PS4 Edition over three days.

Ugh, I hate this cross-gen crud. Well, here's hoping it's something good. BUT, remember, games like Project Souls and TLG would obviously not be streamed on Twitch so those 2 are definitely not the only unknowns coming from Sony
