Urf Warwick in Store: for how much longer?

As all the QQ threads on Urf warwick price have commented, the ceiling is pretty darn high and has a smaller niche. While I love the skin, I do not care to devote an intense amount of effort to grind up blue essences in a short period. Has Riot or can someone from Riot comment on how long this skin will be in the store to buy?

Honestly hope it's open for all of preseason.
