PVP and MAT's confirmed??

In the linked article, And of course the team deathmatch and domination etc modes of first-person shooters are as popular as ever. Will Destiny be offering these as well? [b]There are co-operative or competitive modes in Destiny, you can go and do whatever you feel like on that particular day. [/b]You take the same character with you, so all that persistent customisation, upgrading of your items and weapons, that all carries across. But we're only showing the co-operative experience at E3. It appears that there we be some sort of "competitive modes", I wouldn't be surprised if that's like co-op halo, GOW horde or even some sort of PVP like WOW. (death match and CTF) Also it appears you can collect MATs to create items "One time I saw one of my buddies, a guy that I work with, and he was just gathering materials. So I helped him, we teamed up and went around the public area, spent some time killing guys." What do you guys think
