I think it is because they are really really close now. Mario and Sonic keep getting crossovers, the two latest Sonic games are also published by Nintendo (hence his return in SSB4). And Sega isn't doing much with the rest of their adventure-type game series (and I think they can bring back NiGHTS as game series again for example).
