at this time I don't know a single person "leaving thailand to go get a visa" :O
I wouldn't recommend it to ANYONE right now. Sit tight take the amnesty and see what the government says to do when it runs out.
Most thai consulates aren't even open (or if they are they are only issuing visas to people who have started the process to request to get back in).
Going to your home country is no guarantee that you're gonna get a visa to thailand.
