Is Mass Effect 3 worth it?

I just recently got a PS3. Witch now I officially have all all 3 major gaming consoles in my house. With the wii being my sister's, the 360 my parents, and the ps3 mine. I have ME2 for the 360, but I also heard it was for the PS3 as well. I did some research, and here's what I found: I can get all the weapon and armor packs for a 8 dollar bundle, it comes with, Lair of the Shadow Broker, Project Overlord, Kasumi: Stolen Memory and the Blood Dragon Armor on the disc plus the Cerberus card, it has a better engine than it's 360 brother. But it has a price tag of 50 dollars! I got my old 360 version for 20. The only reason why I ask this is because I want to play ME3 on the PS3 with all my weapons, armor, and choices carried over. So is the PS3 version of ME2 worth the 50 dollars? Or should I just wait for ME3 to come out on the 360 and play at least 2 or 3 times a week?
