Nothing as been confirmed yet about the home and away bit. But its been muted the champ clubs will play 4 home games and 3 away games. With more SL clubs at home than away but that's just what the RFL say may happen but nothing's been confirmed so in theory yes we could end up playing 4 SL clubs away from home ( that's if we make the top 4 next season of course) which I'm having my doubts whether we will or not. Just waiting for some quality signing announcements from the club fingers crossed lol.
Format after split has been confirmed. The fixtures are home and away fixtures are predetermined according to finishing position. There's a document floating around that spells it out in detail. Someone produced a possible fixture list on one of other threads for a given set of finishing positions.
