Orders of the main site are looking at a 14-16 week lead time currently. Not to say your order will fall in that time frame, it could be earlier or later, it's an ESTIMATE. Repeat, it's an ESTIMATE, SaberForge makes no guarantees on lead times, they work their best to get sabers out as quickly as possible with the amount of orders they get. It's a small company serving a growing community.
It may still be possible to cancel your order on the main site and order it on Etsy, but that's something you will have to contact SaberForge directly for. The lead times on Etsy are a little shorter (6-9 weeks) so that's a plus, but there's less customization options.
As far as your order goes, the 12W+ is definitely a great upgrade if you have the money to spare, but 12W is still very bright. When it comes down to it, the saber is yours, so all that matters is if YOU like it. Everybody has a different taste in sabers, you'll come to learn that here. Get what makes you happy!
Don't get caught up waiting for your saber, and don't be expecting it to come soon. Place the order, then try and forget about it. If you don't, you'll drive yourself crazy.
Also I really recommend reading the FAQ, it has a lot of information (a lot of which I reiterated in this post) that will likely answer a lot of your questions!
