So do we think the squadron space combat information in SoT will be like the ground battle stuff in AoA?

Have I missed an article that said that?

Just offhand we've got Squadron rules in the GM kit, and big battle maneuvers in AoA... Do we really need much more?

Sounds like the book is expected to cover more how to stage space combat so it fits better into the adventure/campaign format, and hopefully some encounter design tips that'll better communicate how the system works so people will stop sending entire wings of TIEs against their players lone Y-wing and wondering why the Y-wing gets vaped...

No you did not miss an article , just discussion on the Space battles information you referenced from the SoT article.

All I can say is that it was fun to work on, and was the effort of more than one contributor and the playtesters. I hope you'll be pleased with it.
