It could happen. Yes, it is true that everyone misses the now-physical Leaf Blade, with 20 extra power. But Energy Ball has a base power of 80, better than Leaf Blade last generation, and who needs crits when you have Leaf Storm!? Some more offense-oriented players of last generation can replace now-physical Dragon Claw with Dragon Pulse, with 10 more power. Sceptile can now also use the inaccurate but still useful Focus Blast.
Nowadays, though, it seems a lot of OU pokes resist Grass or shrug it off with ease, and the only Grass-types the tier has time for are the annoying Breloom, the boring Celebi and the actually pretty cool Roserade. And, having said all that about Leaf Storm, it only nets a lot of OHKOs with Specs, and switching out afterward is a pain.
Nevertheless, we can all hope...
