Actually, changing labels in help screens is not really a big effort. At least not compared to upscaling the artwork for higher res, properly threading stuff to take advantage of the second core, re-thinking the game button mapping to take into account that there are 2 extra shoulder buttons, 2 more game buttons, and clickable nubs, etc.
Anyway, it's nice to think about "all the work the devs have to do", but please don't use that as an argument. You'll notice that I'm not the only dev who thinks departing from the Pandora layout is acceptable.
Can we now please move forwards and try to improve the proposals we have so far?
As for the "pure Latin" proposals: I think I like Ziz' ABXY WZ proposal most -- at least it tries to make some kind of sense.
I still think a "pure Latin" labeling is not a good idea though, because it is boring and not original at all, but mostly because of Neelix' "confusion with keyboard keys" argument. Greek labels solve that problem, but there is too much opposition to a "pure Greek" labeling, and my attempt to have a "Greek+Latin" compromise also seems to have failed.
I think that the "Latin+elements" proposal (
http://boards.openpandora.org/topic/15880-action-button-labels-poll-3-final-poll/page-4#entry323706) is a good solution. Since it is based on Pandora Latin, communication and backwards compatibility are OK. By using graphical icons, it is possible for applications to unambiguously refer to the buttons. Also in spoken communication, you can talk about "the yellow button" or "the fire button" -- it does not matter much that some people will talk about "fire, air, water, earth" while others say "flame, wind, drop of water, planet earth", it will be clear what is meant.
By adding elements, the buttons have plenty of character/personality, which is nice when you're trying to map game actions to buttons in a way that makes sense and can be remembered (and that will be an important thing if we have 4 shoulder buttons and 6 action buttons instead of 2 and 4 -- it's nearly twice as many!).
