Where to go when Spartan-3A DSP 3400 is full?

Hi,
Just got a question what to do if future needs fill up a Spartan-3A
DSP 3400 CS484. A very quick and unqualified look at Spartan-6 family
show a package called CSG484 with same physical dimensions as the
CS484. Hope to do as few changes on the PCB as possible. Since the
supply voltage is not the same, a drop-in replacement will not be
possible anyway, but I would like to keep the rewiring need low.
Anybody done this or thought of this who would share some impressions?

Svenn,

The supply voltages are the same ... but the pinouts are different.

Xilinx doesn't believe in footprint-compatible parts.

The CS484 package is nice but I believe it is some time off before it
is available for Spartan-6.

For layout plan for an entire rerouting of the design.
