If you truly believe that they won't extend game length and depth with all the extra resources, then feel free to make comments like that.
Game length, maybe, but doubtful. PS2 games were already plenty long, depending on the game; but the capacity for bluray is primarily for accommodating the HD graphics or has been already shown, letting you waste space with uncompressed sound.
What depth could the PS3 possibly add? The games still control, act,
feel exactly the same as on the PS2, they just look a lot better. Actually, the feel a hell of a lot less, since there's no rumble anymore; although they'll be bringing that back soon. Better graphics will make the games more enjoyable(provided the game doesn't suck to begin with), but they don't add any depth to the games. A cell processor doesn't automatically improve the story, the voice work or make the game fun to play, that's all done through the software and exists on every single console; so where is this improved depth you're talking about?
I don't mean that the Wii will fizzle out of popularity, I mean that it won't be the most highly demanded system forever. The motion controls for most Wii games I've played seem like an afterthought, or they were just annoying. PS3's motion controls will also catch up once developers learn more about them and use them to their advantage. I've never felt that waving the Wiimote in Zelda was any more fun (read: less fun) than just pushing a button.
There's only been maybe 3 games that the Wiimote controls were actually tacked on near the end. Zelda, Super Paper Mario, and maybe 1 other I'm forgetting. Everything else was built for the Wii specifically, or was multi-platform and had it's own team designing the Wii controls during the development.
Games that really use the motion controls are the winners for me, but they're few and far between. Wii-sports, Elebits, and RE4 were great because they gave a sense of immersion in the game you were playing by making the controls directly relate to what happens on the screen. Zelda was like, sure you can wave the Wiimote, but it doesn't change the speed/angle/direction of the sword swing. Games like Warioware and Mario Party 8 were plain not fun to me after the first few rounds of the exact same gameplay repeated to me.
So you've played 6 games, 2 of which you don't seem to like the genre period, and another with the tacked on controls. There's still a bunch of games out there with well built wiimote controls, just because you haven't played them doesn't mean they don't exist.
You have a good point about the not for hardcore gamers, but I think that's a poor classification. "Hardcore" gamers go for the 360 because that's what they think is hardcore. I'd be willing to bet that most people who play Halo think they're hardcore gamers. Nobody who plays a console based game exclusively is really that hardcore, since most of them have assistance to make up for lack of range of motion. Keyboard and Mouse will always win vs controller in skill required.
No, they're still hardcore players, they're not oldschool gamers, but they're under the classification of hardcore. Hardcore is synonymous with a serious gamer, they're the ones who would buy a PS3/360 as well as a Wii. They're the ones who are comfortable with a controller and playing games; they don't have to play 10 hours out of every day to be classified as hardcore.
Saying you have to play on PC to be a hardcore gamer is just wrong. Hell, that'd mean my mom is hardcore since she plays spider solitaire. Keyboard + Mouse doesn't require any more skill, it's just significantly easier to use. Hell, the Wii setup for FPS is better than using a normal controller and is the closest thing to mouse+keyboard.
Wii is a great system, and really won the worldwide race to the top, but I feel that in the long run, the PS3 will catch up and make Wii at least sweat a bit about its lead. Gamecube had a better graphics engine than the PS2, but the capacity of the PS2 disks made it win. The same can't be said about Wii vs PS3, but there's potential for balance in the market. PS3 vs 360 is a different story altogether but that race isn't even fair since the 360 is a sprinter, and PS3 is a marathon runner.
PS3's going to have to work pretty hard just to make it to second place at this rate. The price drop will help, but it's not going to be nearly a big enough difference when the gaming library is still so lacking. In another year, PS3 will have the games to justify the price tag, but 360 and the Wii will keep gaining ground that will become difficult to catch up.
