In case you don't it already, TT is coming up with new alu panniers:

They are looking closer to SW-Motech alu cases which has these hard plastic/rubber cushions at the corners. IMHO, they look better than the old boring shape, but not as good as the SW-Motech. Mind you, who knows when they are truly ready for shipment.
