The way I see it all three have some degree of success and some degree of failure:
360 - Good: Increased marketshare (but can it keep it?). Increased 3rd party support. Made online a standard of the industry. Made a successful downloadable content model and distribution model others are copying. Stopped Sony from dominating. Is making a profit on paper if not in reality.
Bad: Failed to take 1st place. Likely will fail at keeping 2nd. RRoD. Failed to be truly profitable (at least so far) due to RRoD. Likely will not earn enough profit to significantly offset massive losses incurred by Xbox and 360. Failed to make Xbox a compelling brand outside of NA (and maybe Britain/Australia). Allowed Nintendo to dominate market.
PS3 Good: Won HD format war. Earning back marketshare from 360. Maintained key exclusives (mostly, at least so far). Converted Playstation from just games income to games/movies/downloadable content income.
Bad: Gave up market leadership. Stuck in a bloodletting battle with 360 for 2nd. Incurred far greater losses than predicted and may not be fully able to recoop those losses. Tarnished their own brand with their own arrogance. Focused on core market and allowed Nintendo unchallenged access to the larger casual market. Lost Japan to Wii. Lost NA to both Wii and 360. Still losing Europe to Wii, but it has a chance at 1st there at least. Failed to make a profit thus far.
Wii Good: Hell, 1st place in all markets, and mega profits are pretty damn good. Increasing not only market share but market size. Increased 3rd party support. Made a profit from day one and showed the big boys how it's done.
Bad: Vastly underestimated demand and throwing untold millions out the window by being sold out for 17 months after release (in NA at least). Failing to win over many core gamers or maintain many that originally purchased a Wii (although Nintendo assumed the Wii as a 2nd console for the core crowd was acceptable from the get go). Reggie did not convince Rockstar to bring GTA to Wii. Graphics are too different from 360/PS3 to allow (cost effective) multi-platform games resulting in Wii not getting many key franchises despite being market leader. Struggling to supply both old market games (SMG, SSBB, MP3, Etc.) and new market games (WiiFit, Brain Academy, Endless Ocean,etc) in satisfying amounts/frequency.
