Unfortunately as of March 2010 there is still no word of the release of a new rugby game by EA.

There is a petition online for the new rugby game but i doubt EA will, hopefully EA develops one.

The Good News on Rugby 2011

The rugby world cup is coming soon and usually that means a interest spike in Rugby and a good theme for the game (world cup). Hopefully EA pay’s attention and releases Rugby 2010, 2011 soon.

Here’s some info i found online:

Your best bet is to go to http://www.hb-studios.com/ and just keep checking there.
HB Studios were the fellas that made Rugby 05, 06 and 08, and they’re currently at work at like, 8 titles. Hopefully one of them is rugby

There will be a rugby2010.
The rugby section of EA get so little funding that they can only afford to bring out a rugby game every second year.
So we had 06, 08 and we’ll have 010, 012, 014 etc.
