I am a hardware guy. Cooling would be a small issue (but additional die shrinks may make it possible) There were 3 generations on Xenon which powered Xbox360 (90nm (2005), 65nm (2007), 48nm (2010+))[1]. Modern processes are 28, 16/14 (10nm is Intel only really and Xenons were fabbed GlobalFoundry) [1]. The 2005 vs 2010 models reduced power consumption reduced power consumption from 177watts, to 88watts (under intensive gameplay) [2]. So realistically there are 2(ish) nodes available 28nm and 14/16nm [3]. Which could likely (best case scenario) halve power down to 50-40watts. Apple TV by comparison uses 1.8watts [4]. Passive cooling is possible, but the case foot print would be larger. I'm not a thermodynamics guy.

[3] 14nm/16nm are 28nm but a different gate style. Features are still 28nm. Also I'm assuming GlobalFoundry is calling their 45nm node 48nm because they called their 14nm node 16nm.
