Namco VS. Capcom: Tekken vs. Street Fighter!?!?!?

On the Eventhubs site, they posted a blog that talks about Namco vs. Capcom. The two companies famous for the Street Fighter (Capcom) and Tekken (Namco) fighting game series. It has been said that Namco will make their version of the game using the Tekken 6 fighting engine and Capcom using their Street Fighter 4 engine. While this is still a rumor, it could but interesting to see how fans react to the news if it is true. Can you picture Ryu doing a side step or Jin Kazama firing Hadoukens? The plus side both companies are umaking their own version of the game, then 3D and 2D fighting fans alike COULD be happy. However Ono said that the Street Fighter 4 series will not stop with the arcade version of Super Street Fighter 4. Is this what he was refering to?
