@Bob well then be prepared to wait a long time. That price is only for this batch of pre-orders, it will go up after these are all sold.

On the price note, let's be frank, R7.5k is not completely insane given the specs. The PRo launched at R6k - R6.5k, The XBO and PS4 were around R5.5k on launch four to five years ago. Heck I remember a friend buying a PS2 on launch for about R5k. way back in 2001/2002. Building a comparatively similar spec PC from scratch is going to run you closer to R20k (incl OS etc, but not a 4K monitor). R7.5k is not that unreasonable given all these factors.
We each have make the pricing decision based on our wants and means. I have a 4K TV, but have no desire to get a 4K console, I don't see the benefit just yet. Maybe with the true next gen consoles I'll see the benefit, but let's wait and see.
