I think they'll revert back to the traditional way next season. When home kits have been released in the past, there are usually comments about it looking exactly the same as a previous kit, so having the halves the way they are this season stops that and may increase sales as a result of it.
In regards to the third kit, I'm wondering if this is why the club turned down Ribero's offer to repreoduce the play-off kit, as they alreadyhad plans to have a remake of it this season and didn't want to harm sales.
