What episode was that? :S
It wasn't an episode, it was the intro to the fourth movie.
On topic, I doubt it's ever going to happen thanks to the bad reputation the seizure ep gave Porygon.
I don't really care about Porygon not appearing again, as I despise the wretched digi-lump, but Porygon2 would be nice, and it has potential for a good episode. Here's what could happen.........
The gang win a tour around Silph Co., and while they are being taken around they are showed some people attempting to make an upgrade for Porygon. However, Team Rocket steal the upgrade, use it on a Porygon (evolving it) and use the new Pokemon to enter cyberspace. They then start deleting and hacking computers all over Kanto, and it's up to the gang and a young upstart scientist to stop them. It would be a two parter, and it would end with the scientist proving himself by hacking into the computer mainframe for all of Kanto and deleting all the Porygons. Because of this, Team Rocket loose there steed and are lost into cyberspace........ Until a few eps later, when they escape to Giovanni with the upgrade, and he uses it to activate a massive mecha he's been constructing!
*Ahem*
