There are a few things that come to mind when seeing this:
It,s probably something that,s will be a game changer or something that will intergrade the iphone and ipad more into desktop realm. Can,t make this statement by it just being a app for the iphone or ipad.
1.Cubase 7.5 with a supporting app for the iphone (to control the software from your iphone).
2.Groove agent 4 with a supporting app for the iphone (to control the software from your iphone).
3.New hardware with a supporting app for the iphone.
None of these change anything as there are gazzillions of apps for controlling DAWs from smartphones/tablets already on the market. The slogan would be “We finally caught up to 2010 on Nov 14th”
