"Processing time is 2–3 weeks."
The original 5x is fully capable of using the elevation data from the maps yet garmin has yet to implement it. Also the GPS chip is fully capable of using the galileo network but they refuse again to update it for us.
Nice timing! I just got my 5X last week and now they release the new plus(es). I am glad I got a fat discount on my (new) 5X cause I wouldn't want to pay the new "plus size prices" anyway. :D
Garmin Pay and music means nothing to me since I would carry my cell phone anyway. Map in 5S is nice for people with smaller wrist size and wear the watch as daily watch. But I would want bigger screen for maps since my eyes are bad, meaning I would need at least 5. The new sensor on 5X is good, but do I need it? All the other minor upgrades are nice to have, but again, I probably can live without them.
Anyway, I would take a fat discount on 5X over the pricing for the new 5 plus sapphire or the new 5X plus.
But that's just me.
