Some of the preview translations are oddly off, so I'm going to redo them here.

Spoiler:

Ep 13. Castle of Winter
Releasing her noble phantasm during her intense battle against Rider, Saber exhausts her magic powers and collapses. Knowing that Saber will disappear at this rate if nothing is done to replenish her magic powers, Shirou becomes depressed at himself for not being able to do anything.

１４話「無限の剣製（アンリミテッド・ブレイド・ワークス）」
イリヤに捕らわれてしまった士郎を救い出すためアインツベルン城を目指すセイバー達。
イリヤの不在時に城に潜入し士郎を連れ脱出しようとするが…。

Ep 14. Unlimited Blade Works
Saber and the others head towards the Einzbern castle in order to rescue Shirou, who was captured by Ilya. They try to infiltrate the castle while Ilya is away and escape with Shirou, but...

As for the direction, it's clear enough from all these previews that it's going towards:

Spoiler for game stuff:

Fate route. But the title for episode 14, Unlimited Blade Works, suggests that something from that scenario will appear here.

Maybe rather than Archer killing Berserker 6 times before dying like he did in Fate, Archer will use his UBW here and pwn Berserker?

I don't doubt for a moment that Archer is the Archer from UBW, all those "hints" towards Shirou suggests he never had any memory loss.

As for Rider, she's had her moments, but if episode 12 is true, then we can kiss goodbye to Heavens Feel.
