Do you think that the psp go will be a big success or will it crash and burn?  

I think the PSP go will be a hit. :) I can feel it.

When ps3 came out everyone was like its gonna go down the drain and bla bla and yet so many people own one of these console right now.I dont think there was a great difference between the sales of wii and ps3 ,but since Sony is filled with giant cooperate minds they are always able to work out a way i guess, so even if PSP go sounds like a failure(without the UMD) theyll do something to gain it sales,like they put animal planet game for psp go this time :P ...And not to forget there are awesome psp hackers still sitting in Mexico and Russia help us get free stuff or custom firmware :P

It will crash and burn hard, its not worth the cost of a full system. And, to correct you, it doesn't feature cartridges, it has 16 GBs of flash memory that you have to download games onto. So, when you run out of memory, than you can't get any more games. I think it will be bought by Sony fanboys and thats it.
