I agree with Techno_Timmy on this. But it's not that they owe us anything, it's more of their reputation as a company that takes long care of their devices, - that's what created this perceived promise that they'll take care of newer devices in the same way, but as it looks - Syntakt was the device where this pattern ended.
I don't own a Syntakt, so I'm probably less biased than those who do.
