I wouldn't mind if the club wanted a blue & yellow 2nd strip, which of course they could still wear at home on occasion if they so wished. Unless I've missed it, what is the supposedly 3rd strip or is it another secret?

It’ll be the usual red strip used for away games in recent years. The Warrington lookalike/Wimbledon kit should have been reserved for a special event like the quartered shirt which featured at the Blackpool Summer Bash weekends.
