I think that Modern Warfare 2 will have vehicles judging by the second trailer. Also, there should be achievements for CoD MF 2 multiplayer. Like getting to the highest prestige at the highest rank. And maybe they should replace the challenges with achievements. That would be a lot. Plus, they should add like hundreds of guns. Seriously, there are so many modern guns they can choose from, and they should definitely improve on the graphics. MF 1 and WaW used same engine so i'm hoping for something more up to date. They should also make it so that you can ACTUALLY PICK UP A DEAD GUYS GRENADE!!! I makes me so angry, you throw all your frags and your' re done. What idiot came up with that. And, you should have a much bigger inventory, so you can have around 4 grenades, an RPG/AT-4 or possibly Javelin, and C4/Claymore. That would be nice, just like BF Bad Company. There should also be classes. Just a suggestion.
