As an industry standard, Maya Need a really powerful and procedural Particle System just Like Thinking Particles from Cebas.
Every 3DCC software is going to have an undestructive node based system or it already has one, and Maya should have such a thing soon...
A unified Dynamic Solver including Particles, Fractures, Dynamics, Flow, Fume, Cloth, Hair... Maybe it's the next Bifrost.
And beside this Maya should have an undestructive workflow for everything, 3dsmax stack is much better than Maya's history, and Houdini is far more powerful in VFX, even the RIP XSI has undestructive workflow and ICE.
So Please Consider it for future releases.
