The Voyages are the Season Sets. Seasons 1-9 are already available in full. Next will be Season 10, but they are focusing on Collections right now, which essentially combine multiple parts of the voyage sets at a cheaper price. You have a long way to go until you reach the end of the dub if you just started. There are almost 600 dubbed episodes right now. You would need to watch over 10 episodes a day to catch up to the dub in just over 2 months, so the next season will probably be out if you only watch a few episodes a day. It is best not to binge a long-running series like this anyway, unless you are already caught up from watching it as it released..
Eh, I'm in no hurry, really. lol
