I'd like to see several options in commentation such as the WWE series had, so the commentators are relevant to which teams/competition. I'd submit Grant Nisbett.
My George Hook suggestion is as genuine as the sun is bright. I love ole Hooky! In fact, I'd say they could rebrand it George Hook's Rugby 2012 (like the Madden US Football Series). While that may never become reality, I do think Hook is great colour commentary and could ad some fun to the game.Just a note, if comical jests about George hook and Brian Moore are popping up left right and centre, I guess that tells HB we're not too worried about forwarding genuine suggestions on this subject. The last few iterations have featured comments from a Northern Hemisphere commentator and assistance/comments from a Southern Hemisphere comments man.
Perhaps we need to suggest/nominate a commentator and a comments man? Fair enough them both being suggested from your own familiar local favourites, but chances are they'll pick one from each hemisphere.
In that case, I suggest:
Commentator: Grant Nisbett (Won't get picked because he's not an international rugby name)
Comments: Murray Mexted (Absolutely hilarious with a better script than '05)
