"i dont wanna buy a macro just to have it made obsolete in couple of weeks.?"
I can't see the macro controller being obsolete for quite some time. Probably years.
1. i really like the 6 tac bottuns and basically that is my favorite feature, will the new controller have tac buttons?
Yes, but likely less than six.
2. Will the new controller have the ability to have pages of macros or is it presets just like thors hammer?
Presets, more than likely.
3. is the new controller only for MW3, because i like to play the halos and the GoW and ocassionly a racing or sport game so i need a controller for all?
All FPS games. Not racing or sports.
4. i will most likely never use the recording and playback feature and will there be sort of a macro librayer for the new controller?
Why not use the feature? And the new controller will not have a macro library.
5.since you are having a new control will you forget about the macro librayer and allow it to get glitchy and stop making and rating new macros?
No, I will be maintaining the macro library, creating macros, etc.
6. finally which controller should i get macro? or wait for the new one?
The macro controller.
