the mega128 is a different processor... arduino won't work with it
Yeah, I think it's pretty weak to market this as an ArduinoTM Mega, including the almost-trademark blue soldermask, when it's not Arduino-software compatible. It's not entirely clear if the Arduino guys in Italy have granted Seeed the right to use that trademark for the hardware, but it doesn't sound like it.
I'm not sure what a "god member" is, but it sounds rather scary.
it likely means new products will need to be much more secretive, and thus the distributors wont get any advance notice.
In fact, I think the Arduino team is to be commended. Being able to have Arduino-mega in the hands of REAL USERS on the date it was officially announced is a real accomplishment. The distributor pipeline is primed with product and ordinary users can order one immediately (and apparently receive it slightly faster than the distributors thought!) That's practically unheard of, and it's wonderful!
