In response to the Namco arcades at malls :
There is one right across from me that is unmanned. They currently have three or four games offline and for some reason they never get them fixed even though I see a tech in there on occasion. The only time I talked to the tech though he was a total a-hole.
Back into the industry:
To give you an idea of the arcade releases this year, I have a post on AH about the Game of the Year. All of the games on that list were released this year - if the industry were dead, none of these games would exist

Some games that should be of interest but I am not sure how much discussion they have got here are:
H2Overdrive - remake of Hydro Thunder, put together by the same team who did the original and overseen by Eugene Jarvis. This game takes everything about HT and makes it better, it has outstanding graphics and the replay value is much better than just about any other racer out there. The price is pretty good for a 42" screen game as well, it's priced at the level of a standard racer.
Tank! Tank! Tank! - this essentially a remake of Namco's Tokyo Wars but they actually gave it several levels this time (that was my biggest complaint about TW - it only had two levels and thus felt like a demo instead of a full game). It's insanely fun and has a lot of focus on co-op play although there is a deathmatch mode
Razing Storm - Crisis Zone meets Gears of War. Done by the team who has done all of the Time Crisis games. It looks and plays very well but I haven't seen them at many places yet as the cabinets are very expensive.
Textminator - an original game based upon texting. It's fun but I do wonder how it will hold-up as mini-keyboards for texting become more popular.
Tetris Giant - this is a cool concept and it's nice to see puzzle gaming return to arcades. Only problem is the price tag, like Razing Storm will probably keep a lot of places from getting it.
Next year we've got a lot of games coming out that should continue to help the industry to grow: Terminator Salvation, Dead Storm Pirates, Sega Card Gen MLB, NASCAR 2 (w/ internet play), Metal Gear Arcade are a few that we know of already. We also have promises of some big things coming along from a few of the companies behind the games mentioned above - Sega revealed not long ago that they want to focus on innovative gaming (sadly I don't think we can consider their Daytona remake Sega Racing Classic to do that, but ideas like Sega Card Gen and Tetris Giant are steps in the right direction) and Eugene Jarvis recently said "...you will see some crazy new stuff from us as soon as next year! I really enjoy pioneering new game technology..." so who knows what that means exactly but I have heard that they have some very interesting projects going on at RT at the moment.
Also, sorry to be long winded here but Stride Gum also has a Save the Arcades campaign going on right now where you can nominate your favorite arcade to win some cash to help them out.
And I almost forgot to mention, Stern Pinball got a new investor and they are drumming up a new business plan. So hopefully that means in 2010 we'll see pinball start to make a decent comeback with new games that don't look like they could have been made in 1993
