I don't know if you saw all the wonderful threads about speculation for this year's game... everything came up, and the same will happen in the upcoming offseason. Lavery is a funny guy, sometimes he'll throw out an idea he thought of. For all we know, he thought of it while on stage and just said it, and by now he isn't even considering implementing something with IR sensors. It's all in good fun, don't believe everything you hear
They're not going to give you enough bark to bite on before releasing the game next year. Plus, if they do "force" you to use IR sensors, teams can still do dead reckoning systems or use sensors similar to the StangPS and similar things I've seen with other teams. I'd personally recommend that you look more into things like Wildstands Positioning System (StangPS) and learn how to make systems like that in preparation for next year, and not so much on how to find an IR beacon
