[SPOILERS] The similarities between the recent heavy blades and the Blade of Olympus in God of War

[Cephalycion]

"I offer you more than help Kratos; I offer you power! I offer you the Blade of Olympus; it was this blade that ended the Great War and defeated the Titans! Drain your godly powers into the sword Kratos, only then will you reach your full potential."

This is the quote from Zeus in God of War II when he cast down the Blade of Olympus to help Kratos defeat the Colossus.

Now let's have a look at how this thing looks like:

If you think that doesnt look like the Gram Prime in the slightest you need a checkup.

Also, the way that Zeus said "it was this blade that ended the great war and defeated the titans" and also the way that it was offered to Kratos (stuck into stone) was very similar to the way Ballas offered the Paracesis to us.

This is great.
