Anyone else looking to replace their accessories with USB-C once the got updated?

It seems that USB-C iPhones are on the horizon. There’s a high chance that the rest of the accessories that still uses Lightning port will get updated with USB-C port. I do have have the MagSafe Battery Pack and Duo Travel Charger. Having them all in USB-C seems like a breeze as you don’t need to bring Lightning cable anymore but the transition would be expensive. Anyone replacing all their Lightning accessories once they got updated?
