FYI licencing: In the Rugby 20 Beta Wales, France, Ireland, Scotland, Italy, Tonga, Samoa, USA and Georgia all are licenced.
Big Ben has also already indicated they have licenced Top 14, Pro D2, Gallagher Premiership and Pro 14.
Rugby Challenge 4 definitely has the licences for All Blacks and Wallabies.
The absence of England, South Africa and Argentina in the beta suggests these too will also be in RC4.
This leaves the following WC teams possibly unlicenced by either title: Namibia, Canada, Japan, Russia, Fiji and Uruguay.
The fact that the Gallagher Premiership is in Rugby 20 possibly doesn't preclude it from being in RC4 as well. This is because it previously appeared in RC3, Rugby 15 & 18.
Hopefully as in the past RC4 has Super Rugby, Currie Cup, Mitre 10 Cup & Australia's NRC.
Wonder if either title has a RWC 19 licence so that you use fully licenced teams in a RWC mode but not outside the mode in a similar way to the Fifa 18 WC dlc.
