Id say just wait till the tools are officailly realeased since we know they work and they used the new version of x3editor, also i should point out since egoosft did mention they intend to support the mod comunity id take them at face value. they dont wasnt to piss off people who supported them for years
as far as others theres no reason to belive you cant go fiddiling the files yourself, its reasonable to assume you will anyways even if people say you shouldnt, natrally people are curious creatures, forbiding them is like saying don't eat the cookies johnny... hes gona do it anyways because you said not too.
since ego used x3editor in tc id have to say they either have the source code or have adapted to thier own needs this would account for the code number changes, while doubleshadow may be under a nondisclosure agreement, this may be why he dont want to be associated, it may violate some agreemnet, undertandable if hes not then.
i still belive waiting is best, but i know you guys, hahah your gona eat the "cookies" anyways..
cheers..
