The video showed quick donning masks for the Cirrus ISTR.

This makes little sense, there are several single-engine aircraft certified for flight above FL250 and operated single pilot; this is nothing special.

I am not saying the rumour that they have pressurisation issues is wrong – they may well have difficulty meeting the requirements of FAR23 – but they are not that special and are met by quite a few aircraft, ancient and modern, single and multi engine (TBMxxx, PC12, Piper Meridian, Aerostar, …)
The FAA changed the rules: The altitude was lowered from 33,000 ft to 25,000 ft in FAR 23.841, Amendment 23-49.
Older SETPs got higher altitudes before they changed the rule. BTW: The change was prompted by EASA.

BTW:
- All of the TBMs are technically 700s that is based on the 700 Type Certificate, certified 1990
- The Piper Meridian is based on the PA46 Type Certificate, 1983
- The AeroStar is a piston twin so has nothing to do with SETP
- The PC12 is the most recently certified : 1994
As you can see, it’s been over 20 years since the last SETP was certified. Lot’s of experience since, some of it not very pleasant …
Presumably that means that not just the Cirrus jet but also the Epic Dynasty / Kestrel (or whatever it is called today) will be facing these problems if they ever get certified?

Yep
Interesting… so the goalpoasts have moved.
Coincidentally, another one out of “certification takes longer than you expect” book – last year, Piper “Launched” the M600, basically a Meridian with a new wing and higher payload, with the view of certification “this fall”, i.e., sometime in the last quarter of 2015. Didn’t happen, cited reason was FIKI…

Yes. These single pilot (PPL) turbines have shown themselves to be very accident prone. The Cirrus will be right in the cross-fires.

Provide some proof of that. Cirrus has the ONLY jet with a parachute. Single engine turboprops like the TBM have none.
A landing under the parachute is an “accident” as well.

Stop being so touchy. The new Meridian, the Mustang, TBMs etc all cause (or caused) certification challenges as they are marketed at private pilots. The Mustang was designed to be sold to àb initio pilots and my understanding is that drove a lot of the design decisions. It also led to a lot of scrutiny during certification. The accident rate goes down as you get to larger SETs which are more typically flown by professional crews or which have full type rating regimes.
The M600 is taking longer to certify than planned and it is really just a Meridian with a redesigned wing and slightly more speed and range. But the PA46 accident record is poor right now and regulators know this. The first single pilot single engine jet will be very heavily scrutinised.
Of course a parachute will help certification but it won’t give it a free pass.
