Dragino shield with 433MHz chip

Good afternoon all. A quick noob question: I have a Dragino LoRa shield with an 433MHz chip.
According to the wiki (https://www.thethingsnetwork.org/wiki/LoRaWAN/Home) TTN support for 433 will be implemented “later”.
Should I get an 868 to start playing or just wait for “later”?

As a reply to my own noob question: don’t bother with the 433MHz shield when you’re in Europe. Just use 863-870.
