Out of the information list, here are my ideas...
Vehicles will be in MW2- I really must protest against this, it will take away the CQB feel that was a huge factor for me in why I loved MW1
M40 will return, ACOG damage boost will be fixed- just out of wonderment, is this the m40a3 sniper rifle?
Scorpion, P90, M21, R700, G3, G360 will not return- I hope they have found more enjoyable weapons in the case that they are not included, as I found these are good guns :/
New sniper rifle: SR25M (United states forces)-Correct me if I am wrong, but is this not the silenced sniper rifle from TC Rainbow Six Vegas?
New Assault rifle: Diemeco C8 (Canadian forces M4 equivalent)- This is the version of the gun the SAS use, so hopefully that is a hint that they are returning as well

but I must ask what is the point of having this gun if the M4 is in it or vice versa
New Assault rifle: L85A2 (United Kingdom forces)- If this is indeed in the game I will be very happy but I would also want the L115A3 sniper rifle (Uk forces again)as it is mythical, that means the L115A3 Infinity ward, i want that gun, not the older L96...
FavoriteModern warfare 1 maps will return- Is a vote taking place for this?
Helicopters, air strikes, UAV will return- Good as they were balanced, bad as theres no growth...
Snipers will have special grass camouflage (As seen in Modern warfare 1's campaign)- This makes me happy as I wanted this in MW1
All perks will return from MW except eavesdrop and others will be altered- Maybe I was the only person to use this lol
All gametypes will return from MW and all will have hardcore versions- As long as team tactical remains I will be happy with gamemodes. I do not care for hardcore as it feels cheap due to m14, g3 one shot killers
Killcam save feature- This is good
There is blood and gore- I wonder the scale, are we talking MW1 gore? red chunks when you headshot with a rifle? or WAW limbs a plenty
Offline/Online Co-op- If it is done well and not tacked on I will be pleased
Story takes place in the Middle East
Role as US marines return- TBH I didn't enjoy this as much as the SAS role in MW1
Release is set for sometime in November- the 10th of November in the Uk according to the teaser trailer, which can be viewed on IGN.com
New army tags will be available to add different elements in campaign (similar to halo skulls)- I am unsure on what this means so any clarrification from anyone would be appreaciated
So yeah there is my view on the more important part of the list
