Toxic, deluded fanboys are still keeping them alive in discourse.
As for the corporations themselves? Debatable.
Sega Genesis/Mega Drive vs. SNES/Super Famicom was perhaps the most famous console war of all-time, thanks to Sega's jabs in North American marketing against the aging NES and later the SNES.
PS1 took some shots at Sega and Nintendo, and they annihilated the Saturn globally and beat the N64 by a lot as well.
Xbox 360 vs. PS3 was a really close console war. PS3 only outsold the 360 by a few million and the 360 sold more software.
Microsoft acquiring so many studios seems like a massive escalation of the "console war", but I think that's just Microsoft trying to get as many IPs on Xbox, PC, and possibly mobile one day as well. Maybe Microsoft will even put a lot of their games on Nintendo or PlayStation as well.
