There is a new Amiga being developed. It is an accelerator board with a brand new 68080 processor. The thing is, it being FPGA, it actually doesn't need to be hosted in an actual Amiga any more. Therefore they are planning to make a standalone, essentially new Amiga. The Apollo 68080 Accelerator - New Amiga: http://www.apollo-core.com/index.htm?page=products
Also. This is what Amigas can do in 2019:

A new "Amiga" would be something completely different than the old Amiga (which has long been surpassed by PCs with high-end graphics cards) or the current software/hardware model of a PC (which could be improved in many ways if you decided not to be a slave to current hardware and software standards).
I'm not sure what that means, really, because creating something new and useful is a hard (but not impossible) task. It really does take commitment in these days of software that is POSIX everywhere and (graphics) hardware that is sometimes interesting and high performance, but very buggy and effectively, probably intentionally, undocumented.
It's a standalone board that runs Amiga Firmware and boots the Amiga OS. As such it is a new Amiga.
