There will be a max of 100 units that are signature. Please earlier posted response. Thank you for your support.

We won't know till we get towards the end of development how much of a speed increase it will have but we are aiming for 25% for the signature models and it will come with an account that will include free access to Satoshi's Cloud, essentially 0% fees for managed services. There are some other benefits that we will disclose a later time like cosmetic adjustments.
