So it seems like Foxtel and Fox are set to broadcast about 20-30 AFL games next year in full 4K to those with the IQ4 box, has / is anyone upgrading to take advantage of this? And thoughts about the upgrade?

It's a noticeable difference going from channel 7 to Fox, it almost makes the free-to-air broadcast unwatchable, I'd like to think the further upgraded resolution would make watching even better.
