Hexes are one of the stretch goals for the Kickstarter -- if they reach $200K. Right now they're at about $66K with 11 days to go.
Personally, I have a mild case of Tact-Tiles envy, but they just won't fit into my budget. That Paizo Flip-Mat is less versatile than a set of Tact-Tiles, but it's a little more area than an Economy Set of Tact-Tiles for a fraction of the price.
If one company was able to make Tact-Tiles without a kickstarter, then a different company (assuming that this is a different company) should be able to make them with a $66K budget. Just saying. The internet suckers a lot of people in with kickstarters.
