I've been looking into the Titan one and Cronus max, the thing that puts me off with them is that they both seem to need a Windows PC running the software to convert the controller inputs into something that the Xbox can recognise, not a major issue I would say as I would imagine a lot of us have one we could use, but all the trailing wires would drive me mental, I may get impatient and go for it, but there's a couple of things that are encouraging me to wait, first is a bit of secondhand info (so I make no guarantees as to validity) about statements from the boss of mad catz (whom I think also own saitek and made Xbox 360 flight sticks) that make it sound like they're developing something.
Second, and most encouraging, is news that Dovetail games are working with Microsoft and are going to bring their flight simulator to Xbox in 2016, it's based off Microsoft flight simulator and is likely to be impossible to play without HOTAS, not only that, people have been known to spend tens of thousands on setups to play Microsoft flight simulator so it should become worth it financially for Microsoft and flight stick makers to give us a setup we can use.

My thoughts exactly. Although the promise of Titan One sounds great, i don't know what else i could utilize it for in the future if a more direct device comes out soon afterwards.
