Is My Shop a permanent fixture?

I loved My Shop. I purchased 4 of the 6 skins, and 2 of them I can honestly say I probably wouldn't have purchased otherwise (they were more expensive skins discounted 60-70%). I know the current round of skins on the shop are going away in a few days... will it be replenished with new skins, or what are the future plans for this feature? There are quite a few legendary skins I wouldn't purchase for full price and they don't go on the regular 50% sales, so this is basically the only chance I pick them up.
