I think he's moved there already and will be there for the remainder of this season.
The story from the Eels website yesterday stated he'd be there from next year...

Pirtek Eels sign Ben Roberts

The Pirtek Parramatta Eels have signed former international Ben Roberts to a two-year-deal from 2012.
Roberts’ signing comes on the back of Chris Sandow’s recent decision to join the Pirtek Eels next year.
Pirtek Eels coach Stephen Kearney said the Bulldogs pivot would provide further depth to the club’s solid base of existing talent.
“Ben’s played at international level and while he’s had a hard run with injuries recently, we know his potential,” Kearney said.
“We’re looking forward to having him with us next year and being a part of what we’re building here.”
Roberts, who last represented the Kiwis in 2007 and has since appeared for Samoa, said he was excited to be joining the Pirtek Eels squad next year.
“I’m happy to have my future sorted and I’m looking forward to the next chapter of my career,” Roberts said.
“I’m really excited to be playing under Steve next year and want to thank the Bulldogs for everything they’ve done for me for the past six years.”
Pirtek Eels Chief Executive Officer Paul Osborne said Roberts’ signing was another positive step in the club’s recruitment drive.
“We’re building towards something big here and to sign someone of Ben’s calibre is another great sign of the direction we’re heading,” Osborne said.
“Ben has plenty of experience that will add a lot to our club and I know he’s excited about the opportunity to play under Steve Kearney.”
