Casting spell requiring material components when pinned

[Erez Ben-Aharon]

Looks like after the last errata changes the Pinned condition reads:

Pinned: ...A pinned creature can take verbal and mental actions, but cannot cast any spells that require a somatic or material component...

But under the Concentration rules:

Grappling or Pinned: Casting a spell while you have the grappled or pinned condition is difficult and it requires a concentration check (DC 10 + the grappler's CMB + the level of the spell you're casting). Pinned creatures can only cast spells that do not have somatic components

With no mention of the 'no material components' restriction above.

What gives? Can I cast V/M spells at all when pinned or not?

[David knott 242]

Do any spells with V and M but no S components exist?

[Saethori]

Spells cast with Still Spell metamagic can potentially be V/M, with no S.

What this means for the material component is a very good question, if you can cast it with your arms bound. Perhaps it magically vanishes from your reagent pouch?
