The Presonus website says the Firestudio is "based upon" the Firepod. My guess is that it is an improvement - a second generation - of the fp10. I have the Firepod and am pleased with it. The Firestudio would be the better one. The Firestudio also has 4 monitor mix outs.

will the firestudio interface daisy chain with the fp10 i was gonna daisy chain two to get 16 channels to be able to record and do live sound as well

That I cannot answer. Ask the manufacturer on their website. Probably will though, as everything is based upon standards. But that is mere speculation on my part.

Looks like the biggest difference between the two is I/O options - the Firestudio has 2xADAT I/O, BNC, and so on.
Plus, it has that nice CAT-5 connection for the optional MSR - a great device, and one that I have struggled to replace properly when I replaced my Firestudio.

You should be able to daisy chain them, as both have two firewire ports.

Do you already own the FP10? If not, go for the Firestudio. It is more expandable in the long term. ADAT is nice if your external preamps/interfaces have it.

According to the PreSonus website and forums, you can't daisy chain a FP10 to a Firestudio. You can chain two FP10s together or two Firestudios together, but you can't mix and match. I think you can chain a Firestudio to a Firestudio Project or a Firestudio Tube, but I'm not absolutely sure. Check the presonus website. I owned two FP10's and quite liked them. I also tried a Firestudio Project later on for about a week, sounded quite good, but decided I needed something different so I took it back - the problem wasn't sound quality, they were decent interfaces, and for 8 channels a good price.
