I am positive that .TV will cut out a niche for itself and will rather go along .com than competing with it.
I talked to my teenage nephew the other week and we discussed a German music channel;
Viva.tv. I asked him what he thinks about that this channel has a .tv extension and not a .com or .de and he asked me why it should have another one than .tv in the first place. He grew up with it, watches the channel since 2000 and never knew differently.
Shows that a whole new generation will grow up with this extension without questioning it.
