Nope, IIGTR these are plans for an "improved" GTA02, when we might get 
EOL-problems to get glamo chips for mass production, at some point in the 
Right now MP is going to produce devices with glamo, I don't think there will 
be *any* acceptance for delay due to "don't-like-glamo" related redesigns. 
(unless we find a magic trick to replace it with some 0Ohm resistors, without 
changing any of the other circuitry, certs, production tests...). These 
devices have passed DVT and even PVT (most part...) and for sure there won't 
be any change just for beauty of design any more. Fab ramps up...
