I hope this is not the case as it would be a massive cop out. Going from over 70 teams in 08 to 20 is not really representative of the advances in games consoles. The gameplay would need to be out of this world and even if it was that would only bring it up to the standard of Jonah Lomu rugby which at least had 28 teams. The games need to develop over the years not deteriorate. Rugby fans have waited a long time for a next gen game to play and if this lack of teams is true it's going to be a massive disappointment. All the forums have asked for more advanced manager options, Seven's tournaments and more licenced teams. Has all this simply been ignored in the interest of making a fast buck out of the 6 week rugby fans who only watch the World Cups and at the expense of real rugby fans.
I say again, Football World Cup 2010 was not a cop out and that has less teams that everyone would have liked. If you haven't noticed either, Rugby 08 is made by EA, who have lots and lots of money. Rugby World Cup is made by HB, who have not as much money. This means that the game will not be as good as it would be with lots and lots of money. If this game sells then they can make another one after it, and when that comes around I'm sure you and all the others will be complaining on forums at the lack of a certain element in the game to be released. Be happy that one is coming out at all and stop whining.
