My wish is for more drive options. The tubescreamer is already great, but it would be nice to have some different OD's too. An OCD, Klon, Voodoo Lab Sparkle Drive, etc. would be nice options. Also more heavy distortion types. Personally, I was never a fan of the DS-1 pedal. It would be awesome to one day see a Metal Zone, Fullbore Metal, etc. Cool tones to be had running dirt pedals into clean(ish) amps!!
