SuperF, the 135 is in no way related to the 350. Do a Google search for the Bo-108 and you'll see what the 135 started out as.
All OEM's regurgitate old designs/parts into new helicopters. If you look on the 412 you'll still find a couple of parts with 47 part numbers and plenty with 204/205/212. Agusta does the same, the Engine Control Levers in the 139 come from the 109 and the rotor head is an upscaled 5 blade version of the 109 head.
Personally, I wish Bell all the best. Everyone seems to want more of this and more of that, but there is still a place for a basic 5 seat turbine that plods along at a modest pace and is cheap to buy and operate. Just ask Robinson.
