I'd reckon, if the X21/22 has seen growth in line with what some of the other Sapphire routes have, they'll get new buses within a couple more years. Can't remember which route it is but I'm positive I've saw a comment or something somewhere stating that the older E400's used on said route are being replaced this year (think it might be the 280 route).
