what all is going to happon with the halo community?

ok so i have followed halo since it wasnt even out in 2001 and over time iv got to see the game grow into this massive community…well i know only so much for some reason so im gana ask a few questions that im hopeing that will be answered.

1=bungie i know they left the WHOLE halo project to 343i,so i went to bungie.net and looked around so they changed some so i was wondering if they gave it all up then why can i accesse my halo3,odst,reach profiles from there and not halo waypoint?
2=bungie pro and such, are we still going to be able to buy it still?
3=how much of 343 is going to be like bungie’s way of developing the game to make it feel like nothing changed?
4-final= i have a hard time following any of 343’s news that have to do with the games current progress such as weeklys on reach and dose any one know how long its been since the halo 3 bungie fav…oh ya.

so i hope i can be informed on this stuff and what not that way i can become a better fan and consumer :smiley:
