Has GO 2.0 some features from aetp engines?

The AETP motors are supposed to provide ~20% more thrust, ~50% more loiter time, ~35% increase in range, and improved acceleration/lower IR signature.

As an interesting aside, I was talking to a P&W rep over the fall, and he told me they would rather have the US Gov just shelve the competition for new engines. He said their goal was to demonstrate that the current f135 has so much growth potential that the military won't waste billions on a competition for a new engine. Perhaps he was worried GE might have a winner?

I'm sure he'd rather the USG waste billions exclusively on P&W engines. :mrgreen:

I'm curious how the 2-stream F135 can be modified to solve heat buildup in the jet's electronics which AFAIK is currently an issue for low speed low level flight?

No need. Wait for the next TR and then you have few and more capable components that allow for better cooling.

Just to clarify... the electronics will be modified to address the heating issue?

Power and cooling upgrades are common as jets mature and capabilities are added. F-35 will be no different.
