Creativity has nothing to do with gear. It's you that needs to be creative with the tools you've got. Completely re-think your system, make a smaller setup and focus on certain ideas or modules, read Allan Strange's book on synthesis techniques... For sure you'll get creative again.
Also: there's some modules being released that are completely new like f.i. Klavis Grainity, MN Spectraphon (maybe not completely new), phase modulation oscillators... I'd just stop looking at all those new things and record an album with the stuff you allready own. ;-)
perhaps go even further than this... create a single patch - ie a costom instrument and create a whole album with it... you can change the tempo, notes played, any switches and knobs, but not the patch cacles... you'll really learn to play that instrument... then pull the patch cables, create a new instrument and repeat...

Utility modules are the dull polish that makes the shiny modules actually shine!!!
