Round 5 has announced that Vitor Belfort, Shane Carwin, Nate Diaz and Thiago Silva will be featured in the fifth installment of their UFC “Ultimate Collector” series. This series will also include surprise “chase” items as found in previous series.

Collectors should also be on the lookout for surprise “chase” items, which will include special accessories or variants hidden in a limited number of packages available at random stores.

“Our first Series of 2011 has four fighters who have been requested often by fans, and who are all new to Round 5,” said Damon Lau. “Collectors have enjoyed finding the ‘chase’ items in previous Series, so we’re excited to continue that with these new figures.”

“Ultimate Collector” Series 5 is expected to hit store shelves in early 2011.
