I'm tired of PC's, update an A1200 or wait OS4 hardware?

The most sensible solution would be WinUAE, at least with your current requirements.

If you absolutely won't have a PC, then I'd say Pegasos II with G4@1000 and keeping A1200 for old games. Would be cheaper than expanding your A1200 aswell (whole system excluding monitor), and you get much more bang per buck. Naturally this is no solution if MorphOS is not an option for you.

There are some solutions coming "Real Soon Now", but the percentage of the products actually hitting the market has been quite low.

i think that a PPC 603e with a voodoo is enough for VCD or SVCD, or i'm wrong?

It's barely usable, and you get frame skipping (at least I did with my 603p@270 overclocked BPPC).

I read that mpeg2 pci decoders that have a EM8400 processor are also compatible with mediator, someone have a MPEG pci card on mediator?

No, Mediator has no mpeg2 decoder support. It has no mpeg decoder support of any kind, in fact.

About A1 systems, on the Spanish shop that i will buy the hardware, the AmigaOne XE G3 800Mhz motherboard with linux and OS4 price is 798 EUR, the same price that the A1200 upgrade, but i need the tower, and PCI cards for graphics and sound, RAM.

You can get full Pegasos II system (tower, peg2 mobo, 7447@1GHz cpucard, 256MB ram, 80GB HDD, Radeon 9250 128MB, CD-ROM, keyboard, mouse, speakers, mousepad, morphos/linux preinstalled) for 675 eur. That's in sweden at least (closest shop around here).

One question more, last workbench version that can run an A1200 with PPC is WB 3.9, the OS run on PPC or on the 68k processor?

68k. Nothing in AmigaOS 3.9 is PPC by default. You can install some 3rd party PPC datatypes and other PPC components, though.

Exist WB replacements to run on PPC (MorphOS, WarpOS?

WarpOS: no, nothing that would use the PPC.
MorphOS: Ambient, the PPC native desktop

You will have to wait for a very long time (forever most likely) for those being available again. If you absolutely must get A1, 3rd party is your only option for now.
