Thats a big statement to make .. cause this chikun is going to the mooooon lolz.
Me thinks your underestimating the irrational exuberance of the markets .. besides some of the ideas in something like mastercoin may well be incorporated in btc in the future.
The underlining factor on incorporation is "may". Not every coin/DAC being born out of btc fork is supposed to be incorporated in btc in the future. Mastercoin maybe, but ethereum or protoshare or zerocoin or even levelcoins too? Nope, not all of them are going to be incorporated.
Again IMO, if looking for the next big thing, look for something which adds value. If you find a coin which just acts as a value store like most of the coins out now, then you already have BTC. No point in looking for others.
