I think this may be like most wanted, but with episode VII ships, and a way for people to buy in and start playing with everything they need without buying the original core set. that's the only decision that makes sense from a business standpoint.
Indeed. I'm not the first to mention it, but I'd say the Wave 8 announcement makes it extremely unlikely that any upcoming release will substantially alter the rules. Everything you own now will remain relevant, because doing anything else with the license would amount to a massive own-goal.
If X-wing 2.0 ever shows up, I guarantee that FFG will have a long, public lead time and a marketing campaign designed to convince us that we should switch to the new rule set.
