If you type "Moto G teardown" on google, there is an article showing that some group from Germany did it. They were trying to see if it would be possible to upgrade the storage. They confirmed the storage cannot be upgraded, however, they found out that the battery can be replaced.
It'll probably be awhile until there will be battery replacements available. Motorola intended for the battery to not be replaced, so I can only see third parties producing batteries for sale. You know, the ones that claim 5000mah capacity.... lol
Also the moto g battery looked like it wasn't the simple redwire/blackwire/pin-type batteries from older phones or a battery you can just solder on. Its a ribbon with a special connector.
