Sony is planning to reveal the PlayStation 4, or whatever it’s called, this Wednesday. Before that happens, however, Sony has created a little history tour through PlayStation’s past. If you need to catch up on your gaming history, this is a good place to start.

First up, of course, is the original PlayStation. The result of a ruined relationship between Nintendo and Sony to build a CD-ROM add-on for the Super Nintendo turned into one of the most successful gaming consoles of all time. Sony was the first company to market video games to adults and it worked out super well for the company. It even beat out long time incumbents Nintendo and Sega.

Following up the original PlayStation with something even better seemed almost impossible, but Sony did that and more with the PlayStation 2. The PS2 has the distinct honor of being the best selling home video game console of all time with over 150 million units sold around the world. It helped that the console was the exclusive home to many of the generation’s best titles including Metal Gear Solid 3: Snake Eater, Final Fantasy X and Shadow of the Colossus.

All good things must come to an end though. The PS3 didn’t have the best launch, and the $600 launch price was too much for many to swallow. Sony’s console also lost out on many of its exclusive franchises from the last generation as the Xbox 360 was also home to popular titles like Final Fantasy XIII. Regardless, the PS3 hit its stride a few years after launch, and now offers many of this generation’s best games, including Uncharted 2: Among Thieves, Metal Gear Solid 4: Guns of the Patriots and LittleBigPlanet.

Unfortunately, these videos don’t offer any hints to what we can expect on Wednesday. The hype is at an all time high though as the PlayStation faithful are figuratively frothing at the mouth for any and all information about the next generation of gaming from Sony.

All we can say is that it’s going to be big. This is the first true next-generation console debut, and people are already expecting a lot from Sony and Microsoft. Sony can’t really afford to mess this up like they did the original unveiling of the PlayStation 3, and Microsoft will be watching very closely to take advantage of any missteps. The worlds’ eyes are on you, Sony. No pressure.
