No no no, don't worry! If you're thinking everything might be shifting to be browser-based then you've got the wrong end of the stick unfortunately! The desktop application will remain, it won't be changing to a web/browser application.

When I said previously "you'd need to be connected to the internet to use it" I don't mean you'd need to access the mobile version via a browser but simply that the app would need a data connection to a server so you would need to have an internet connection.

For example if you turn off your 3G data and WiFi on your phone you don't have an internet connection so the app would not work in that situation; it'd probably be dependent on the speed of the connection too so slow mobile data for example might make it painful to use. Which is why I'm not at all keen on that approach!
