Good thread/list. I'll add a few more.

Vyacheslav Glazkov 12-0, 9 Knockouts

He's an Olympic bronze medalist from Ukraine. Good size at 6'3 225ish. Defeated Price as an amateur by ref stoppage.

Magomed Abdusalamov 14-0, 14 Knockouts

2005 & 2006 Russian amateur heavyweight champion. Training in Oxnard with one of the Garcia brothers. Fighting Maurice Byarm this Friday on ESPN2.

Bogdan Dinu 7-0, 4 Knockouts & Andy Ruiz Jr 14-0, 9 Knockouts

These two I don't know much about...but I've seen both in action and they appear to be decent. Dinu has great size at 6'5 230. Ruiz is one of those quick-fisted chubby guys. Promoted by Top Rank so I think we'll get to see more of him in the future.
