As you probably know, this isn't the first Sentai figures Figuarts have produced. They also made ones for Shinkenger and Gokaiger, and the quality is brilliant. I got really excited when I saw these, and definitely hope to get them myself in the very near future.
If you're interested in getting them, then I advise you get your order in soon. AmiAmi have already stopped taking preorders for them, though luckily CDJapan still have them available for preorder up until the 15th of May (according to their site).
These figures look amazing, and I definitely recommend you get your order in asap before they all sell out and you are left at the mercy of eBay sellers or auction sites who charge extortionate amounts for them.
