I know one of the reason Alex really wanted to change platforms was because this was supposed to support mobile so much better than the prior ones. However, due to lack of budget and what I can only assume other reason, it never had a proper managed test phase. As a result, there are some issues with mobile like when trying to display details of a deck, etc, but browsing seems to work just fine.
So yeah, I doubt a full mobile app is in the plans, but hopefully he'll be able to come back and fix the issues with mobile in a browser.
Victor - If you can list your exact concerns or why you prefer an app it may be something he would consider. Personally I'm an app guy myself too, but given the costs and especially ongoing costs for support and updates to multiple platforms I can't blame him if he just sticks with the mobile browser approach.
