(DG) Easy replacement of Quantum 1 for Quantum 2? / Quantum 2 with Lighthouse II?

I'm thinking about exchanging my Quantum 1 (connected via WiFi to es98) against Quantum 2 when it's available,

But I wonder about these two questions:

1. Has Quantum 2 the same power connector? That means, can I simply swap Quantum 1 antenna against Quantum 2 antenna without the need to run a new wire?

2. Will Quantum 2 be compatible with Lighthouse II?

Thanks!
