I see three possible futures when this game comes out:
1. Its good enough too take big chunks from both the LoL and HoN communitys, which would kill HoN, but LoL would live on.
2. Its a DotA rip off right down to the core, but its good enough too take away a part the HoN community, but not the LoL since LoL is actually diffrent from DotA.
3. Its isn't better then either HoN or LoL, so it dies within a year or so.
Bottom line is: DotA 2 will not be able to kill LoL. It might be able to kill HoN, but I doubt it.
