I must say the ongoing cost, isn't something that bothers me. I'm glad that i know its there and that it will be a requirement.

I hate the games that you download for nothing and then have in app purchases to be able to get anywhere with the game. They make the games hard to progress without IAP's for game coins/credits. I can't imagine these games have the longevity factor.

I am glad you're progressing the changes well. Do you know what sort of timescale you're looking at for resubmission?
