That is not a new "Amiga", that's just a nostalgic upgrade to an old Amiga computer.
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.
