The most recent system I bought was the Nintendo DS Lite, and that might the last new-generation system I will ever buy. I tried out the Wii not too long ago and found it frustrating to use (I played Wii Sports, Rayman 2: Raving Rabbids (when it should say Raving Retards...honestly, if you've played or looked at the game, you know what I'm talking about), and Super Smash Brothers Brawl). It's the type of system I should practice on a daily basis before getting the hang of it, but it's not worth it (which sucks, since Mega Man 9 is coming out for the Wii, but you use the Wiimote like a regular controller).
Street Fighter IV (which I'm also psyched for, but I won't play right away) is coming out to PS3 and XBox 360, which I also don't believe are worth getting for that game alone. And that the sad thing: I assume others have mentioned this, but the photorealistic graphics/animations take way too much time, are way too expensive (due to the size of teams, their individual salaries, and their positions like art director, animation director, physics director, or things like that), and not enough time is spent in developing storylines and characters (which is what many of the games generations prior prided themselves on: unique storylines (or new twists to old ideas) and memorable characters).
On top of that, prices are rising for just about everything besides videogames: gas (of course, it's been established), foodstuffs, shipping both of the above, building the ships to ship the above stuffs, medical supplies, ammo, etc. As far as games are concerned, outside of SFIV, MM9, and Castlevania: Order of Ecclesia(sp?), I will not invest another cent in future systems, or the fanboyish bullcrap arsenals that will ensue. That's not to say I won't visit stores/fairs/conventions on occasion and find a PS1, Dreamcast, or even a Super Nintendo or Sega Genesis title, but it's too much for me.
If they have SFIV or MM9 being played somewhere, then fine, I'll play it. But I'm not gonna spend anymore just so that I can see individual freckles on a main character avatar's mug, or individual stalks of grass waddling in the dirt.
