It's typical Richie talk , it's vague enough to not mean too much.
I hope for a solo record to come though, but I don't count on it too seriously neither.
Years ago Jon talked about being interested in doing a duo work with Richie (before This Left Feels Right turned out that way) maybe working with Jon could be that sort of thing , you never know..I cannot see the whole band back at work that soon but they will not stay away for too long neither
