Going with a 10 or 11 spd, and fairly big sprocket, one may not truly need a triple, especially if using a 110bcd compact crank. 33 gears is just TOO MANY.
Personally I don't like the aggressive contours on the inner side of the Shimano front deraileurs, and have had troubles up-shifting with them, so I'd choose a SRAM or similar dérailleur over the Shimano dérailleurs. But, you're right that a lack of shifter support could be the downfall of the triples for use with drop-bar bikes (road/cyclocross).
doubles and 1x are trickling down quickly in MTB land. Spend more than $720 on a Trek XC bike in 2015 and you'll be getting a 2x10 or 1x11 drivetrain.
