What is Halo Reach and why does it matter?

[hudsoniscool]

first off by the time halo reach comes out halo 3 will have sold 11m+ copies.so reach is the first full sequel(or prequel) since halo 3 so i see the sales of reach looking like halo 3 or better.
you can say the popularity of halo has gone down but you would be wrong. Odst a 60 dollar expansion is going to sell more then 5m copies, thats good, and exceeded bungies expectations. halo wars is going to sell 2m in its lifetime. its already sold more copies then any other console rts ever. that is saying something.also halo 3 has been first on xbox live activity 99% of the time since its release.
there is going to be double te consoles out when reach comes out then when halo 3 came out(18m when 3 came out 40m+ when reach comes out)you can try to say the casual gamer,or new gamer had no idea that odst was just an expansion. id say less then half the casual gamers/new gamers new that about odst. besides odst ddnt look like a massive awsome game.
odsts marketing campain was decent but is going to be nowhere near reaches.also reach is going to have some great looking gameplay, and the game will look massive(unlike odst)
theyve already said the marketing is going to be bigger then halo 3's and with more then double the potiential buyers that could be huge.
how many copies will it sell
senerio 1- reaches marketing campain is as big as halo 3's and doesnt is basically a copy of halo 3 with same or very simaler multiplayer with decent campain(like halo3). it will sell 10.5m to 13 m copies,
senerio 2- reach has bigger marketing then halo 3. has new gameplay(especialyin multiplayer). has a great singleplayer(could happen since reach is such a great story). it will sell 12m to 15m
thats not a streach the biggest reason being huge marketing combined with double the xbox 360 owners and 3 times as many xbox live users then when halo 3 came out.(important to note as halo games biggest atraction is its multiplayer)
