Anyway back to the kit, seems like the big factor in changing is because Adidas is such a big beast globally that we get little attention/priority and so we have to order our kits 18 months in advance.
So I'd expect us to be going to a suppler who is a bit more local who have more design/production flexibility.
Maybe ISC

ISC aren't really a great soccer brand, they're more rugby/AFL affiliated. I'd rather someone like Puma, they do stripes very well.
Like 2B said, there were problems with Adidas given how large they are and where their priorities sit, and there'd likely be similar problems with Puma. So there's every chance that the new kit supplier will be a smaller/boutique brand that can be more responsive to the club's needs and ideas.
