they are. if Infinite is another let down I think 343i is done.
at that point I actually would expect Microsoft to completely close down all the game development at 343i and either outsource the IP or give it to one of their other studios.
but given that weird no sprint, no clamber playlist and the possibility of it being a stealth beta test for Infinite... I have hopes...
because thrusters and stabilisers are actually the 2 Spartan abilities I would have no issue keeping because they don't limit your movement at all any only expand on it with basically no downside.
all I would want is for the boosters in Infinite to not limit your ability to shoot. in H5 thrusters will stop you from shooting, get rid if that fact and IMO it would be perfect
