Sony teases upcoming reveal

After a successful day for Microsoft at Gamescom it looks like Sony is ready to reveal something new for PlayStation 4. A recent tweet from PlayStation Europe says “We’re getting geared up for the reveal of something new.”

It’s hard to predict what could be under the red blanket because it looks pretty big, but a clue could be a special GT Sport PlayStation 4 Pro, it might be too early to say it is a PlayStation 5. or some might say it’s a PS4 Pro upgrade to compete with Xbox One X.
Would it be a good idea for Sony to make another console already since they already did a PS4 Pro last year and now they could possibly have another in a span of 4 years.
Let us know your thoughts.
