Well, the new items are initially locked to the current ladder season. Of course stuff like balance changes and buffs/nerfs will be available throughout, but stuff like the new rune words, if such will be introduced in Season 2, will also be initially locked to ladder. So you'd have to wait another 4 months to be able to use them in non-ladder.
Also JSP Hoarding just shows how detrimental that site is to the game overall. Luckily not every D2 Player is on JSP either. The whole JSP issue however isn't anything you can blame on Blizzard for once.
