FKIrons Xion is coming out probably around 3 months. Saw Gaston on Instagram live yesterday. He showed running prototype. It has adjustable give, and will have a disposable grip option which is really cool imo. Will come with 3,5 and 4 mm cams if I remember correctly, which are super simple to switch. Looked powerful, solid and silent, as the rest of their products. So yeah- pens are getting way more advanced than this.
