Here's how it's going to be "contextually relevant" while still being set in 2142: there will be old bombed-out cities let from the 21st century that miraculously have all of their ads left intact. Because you know, we can't have the poor advertisers' hard work defaced in any way. Which also makes me wonder if the ads will be immune to damage/decals/etc so they are always visible.
BF2142 is going to suck anyway if the history of the BF series is any indicator.
A message of hope to those who choose to hear it,
and a warning to those who do not.
