Last week, Amazon showed off the NVIDIA SHIELD and SHIELD Pro. Unfortunately, the SHIELD Pro listing was quickly taken down. Perhaps it was an honest mistake by Amazon or NVIDIA still isn't ready to make a major announcement. But no need to spend time thinking if it's real or not because we're telling you it is real. We've seen the signs and NVIDIA could only be preparing for a big launch of the 500GB Pro variant of the SHIELD.
