PSP ultimate bundle - upgrade?

[martb]

I was thinking of going for the PSP Ultimate bundle while it's on sale. I already have the Nitro bundle and was wondering if there is an upgrade path to Ultimate. In other words, would it bring the price down a little more?
Thanks

That option would be cool! From Nitro Bundle to a higher Bundle or from single plugins to a Bundle. Just my humble opinion.

I had the Nitro bundle too, We need a upgrade option to Ultimate !
