It's a tricky knife edge balance.
I'm mobile (Android) only, so would definitely love to see future updates for that platform. Whilst I would like updates, I understand that ipacs are a business and have to chase and develop for whichever platform they see will make them the most profit or expand their reputation or portfolio at the time.
I'm sure ipacs will revisit mobile as they have said so several times. If not, the product we have already is good, it would just be a shame as we're all so passionate about this because we can see its promise and where it could possibly get to in the future. That's why we all hang about here and other ipacs groups.
Mobile is an especially tricky market to handle well though. You have to keep interest going carefully, with news and updates via social media, but on the flip side you have to be careful not to over promise or over inform upfront of updates due to some people feeling over entitled. I do think you have to probably have around three major updates a year on average. Any less and your market dwindles and walks away to other products or genres. Once lost, sales are hard to claw back.
Managed correctly and with a good developing product though it should be huge from a sales point of view.
Everyone has a smart phone these days, Infinitely more than gaming pc's, and purchase from a playstore is instant disposable purchase. You just have to keep your reputation good, product visible and the market keen to buy your offerings.
