First of and having in to account that there's nothing written about tastes...
You may like or not having your radar redendered on your HUD in one of the 4 possible corners of it. However, many pilots might like to have their radar rendered on, for instance, centered in the bottom chunk of their cockpit. Option which should worth all respects too.. The more available possibilities the better. You just pick up the one which fits better for you in the settings. How could that be any bad?
I'll go further and in general terms on cockpit integration..
I honestly think that, in every 3D cockpit for every mech in the game, there's room enough to integrate fuel, heat, Radar, even EU and other things like lights to indicate when weapons are available, when you've been locked on, Etc.
Yes, we had cockpits pretty well integrated in the game prior to the first big game patch was released. The main problem was the pre-alpha code implemented to have cockpits working in HAWKEN at the cost of consuming too many game ticks and causing graphical lag, to be brief here.
But the fact is that, integrated cockpits for your mechs will always make immersion much better as well as contributing with a great dose of coolness factor in HAWKEN.
Again, nothing written about tastes.. however cockpit integration is gonna be something good; always.
P.S. Now I could go deeper on VR, competitive gameplay (reaction time) and so forth.. but I won't do that.. for now. ;)
