Kanon 2002 < I would imagine most people that bought 2006 Kanon wants to see this.
Sister Princess Repure < Its a retelling of ADV's Sister princess Story. Not a sequel.
To Heart: Remember My Memories < Next sequel to Right Stuf anime To Heart.
To Heart 2 & three OVA's < Spinoff of the original To Heart

But only if you dub them, except Kanon 2002.
