As mentioned, I understand completely that these higher tier collectors if you will are getting screwed by this, and as @DayC mentioned I understand this is his livelihood and his business and don't have any issues with him being pissed off. I would be too - my point here however is regarding the idea of the investment, as they are collectibles, just as you mentioned with Oil and Gold the value inevitably changes depending on demand/tax and any number of things.
He himself even states there's been changes coming for some time now with the resurgence of Table Top and TCG's. Whilst few could have predicted another re-release his attitude towards the previous one was a bit different as he 'didn't have many himself' and to me it seemed he was pleased at the prospect - though as he said many assumed this was due to a shorter lifespan etc.
To me it just felt the video was half informative, half entitled to feel that a TCG would be any different to any other investment that can fluctuate and fall at any stage. It's just weird because at the start of the video he goes on to talk about just that, that investments do go wrong when business' change but then by the end of it it just collapses.
