Lots of 420 hate here. Damn. I enjoy that beer and can drink a lot of it. The SweetWater IPA is easily better than any IPA brewed in Louisiana. Great Simcoe aroma on that one. Blue has its time and place. Not a big fan, but it's not terrible. Better by far than any of the Abita fruit abominations.
Not sure on the timetable for other releases. Will see if I can find out tomorrow.
420 isn't bad at all. Like someone else said, good pale and you can drink a lot of them. I like it. IPA is very solid for the price. A regular buy for me. If you like fruity beers, SW Blue is hard to beat. I don't drink it often but they are great ice cold on a hot day. Happy Ending is one that never gets mentioned but it is a fantastic stout they put out seasonally. Keep an eye out for the Dank Tank series. Some great beers mixed in there as well.
