So, the new Guitar Hero is coming out in late October...most of us who have heard about this knows it includes a drumset and a microphone, and for those of us who don't, there you go...It sounds way damn better than any of the previous installments in the GH series, as follows:
1. Obviously 2 new instruments (and Bass, which has different notes and is easier than guitar) will add to the replay value like nothing else could.
2.The graphics are much better, and in depth, so that's an improvment right there.
3.you can customize your characters, and the store has so many more things.
4.The playlist features over 85 songs!Oh hey and Zeypher, we finally got oursleves atleast one Linkin Park song in the game

Here's a screenshot:

Cool, and I like the orang-ish theme...more to come later!
Also, (hopefully no-one will need it) A new mode, beginner has been added, but it is rumored that the other modes will be harder because of this. Oh and if this isn't easy enough, they added Easy Rythm guitar mode, it's either in beat with the drums or the bass, but it's basically just for retards. Another nice new installation, you can not only play online, but you can start a full band online! That means you no longer need to buy the full set to brag you beat the game with a full band!
Time to talk about drums...these drums, unlike the Rockband ones, will include 5 notes, two of them being cymbals. Also, we have the introduction of armored notes, that aren't a necessity for getting 100%, but give you bonus points if you hit them harder than the notes right before armored notes. I guess this means the drums will recognize how hard you hit them to a certain extent. As to what they look like, I'm guessing the red and yellow notes on the middle notesheet are armored notes. Also, Red Octane says that the GH:WT drums will be far less noisy than the Rockband drums.
Anyway, here's a screen of all the instruments together:

Notice the thing under the strum of the guitar? That's a new (but optional) way to activate Star Power.
Oh, and did I mention? Everything is wireless. Yup, say goodbye to plugging in all of your instruments, and then having to untangle them, unplug them, and wrap them around your controllers every time you're done with a jam session, because Guitar Hero World Tour is absolutely wireless baby!
Remember the big playlist I told you about earlier? It definetly doens't stop there...you can make your own songs, trade songs online, and buy songs in an in-game store. We don't know if this will actually be DLC/XBL, or something that goes all to the makers of the game, but whatever dude, downloadable songs! More screenshots:

Character customizabilitly (is that a word?) FTW! Wait, is that a guy or a girl?
EDIT: actually looked at the picture, and whadya know? That's Guitar costomizing right there. Told you so...

Probably what the song=maker is going to look like...looks kind of like GarageBand.

This is supposedly in-game
Wii graphics...damn nice.

More character creation.
Did I really forget to mention? You can create you own guitar in this! Lemme go find some screens...
Damnit, can't find any...knew I saw some screenshots in Jekyll's GamePro...anyway her's the official trailer(s):
