This is what I understand about it...
Sakura won't ever remember about her past relationship with Syaoran BUT I think Sakura can learn to love Syaoran again but not through her old memories. Remember that it always gets immediately erased if she remembers bits of her past. It will just be like Sakura liking Syaoran all over again but as a new Sakura. Her past relationship with him won't be there to influence her new feelings for him although it just be the same in the end... "love".
Anyway, I'm moving this to the main TRC forum since it's not really just specific to the manga.
Actually, i agree most of the points raised by Little Wolf..but on point Sakura's past relationship does affect him, you guys remember when Sakura kissed Syaoran on the cheek? that's when Sakura subconsciously as in physically still remember being close to Syaoran, so when Syaoran appeared to be hurt or bruised, a part of her still cared for him, therefore such intimate action was done....So i think the past relationship still remains in Sakura's physical part..like she still blushes/cares/fidgets for Syaoran. There's another scene when Sakura still forgets her memories, around vol.3 or 4, even though she doesn't have a clue on what the jounrey was about, when she saw Syaoran hurt she felt sooo upset. (that means the subconscious 'love' feelings towards Syaoran might still remained in SakuraXD
But one thing i'm not really sure about is that, Yuuko only took Sakura's former relationship memories with Syaoran rite? so it doesn't mean that she;s gonna take the current 'forming' relationship rite? (hm...i hope not)
