Here are the first Professor Layton Vs Phoenix Wright screenshots.

Japanese magazine Famitsu has revealed more details on the game. You may already know the story which finds Layton and Wright in Labyrinth City during a witch trial.
Wright has to defend a person who has been accused of witchcraft while Layton is trying to make sense of the city's Story Teller who writes things down which become reality.
There's a new gameplay system called Mob Judgement which sees Phoenix Wright in questioning against crowds of witnesses.
Mahoney is the the accused witch who Phoenix Wright defends while Jeeken (the red-haired chap) is the prosecutor in the case.
Professor Layton VS Ace Attorney will be released for 3DS in Japan in 2012.

I want this game so badly
Anything with Layton in is a must buy for me xD
Will be interesting to see how the two art styles mix.
I want this game so much you have no idea...Come ooooon bring it to the UK! Fingers crossed! I'm begging you level 5 and capcom guys, i would love you all forever
I love the Art Style for Professor Layton VS Pheonix Wright! It looks nice and cartoony while still having great graphics with lots of details!
I really hope we get a release in 2012 or 2013, as this looks easily one of the best 3DS Games!
Do want!
I don't think i'd want to mess with a prosecutor who wields a sword! But wow, this game is looking to be my favourite game ever
Need to hear the music though!
If there was only one game I could afford to buy next year it would be this one
Whenever we might get our hands on to play it
Phoenix Wright is my +fav game
and i'll get used to Professor layton who is
either teaming up or against each other
looking epic
I WANT THIS GAME SOOO MUCH!!!!
I am a HUGEEEEE fan of the Ace Attorney series since the beginning and LOVEEE the Phoenix Wright trilogy the best!!
AND THE SAME GOES FOR LAYTON!!!! This game is going to be AMAZING!!!!
This looks awesome, and phoenix looks great in 3D. I wouldn't be surprised with we got another ace attorney game for 3DS after this. I'd be really upset if this didn't come over here. I've never played a phoenix wright game (though I have played Apollo Justice and Miles Edgeworth) but I don't mind.
Intresting. They seem to be using a Phoenix Wright style of view while using the new 3Dish graphics of Professor layton. Nice!
Looks pretty awesome. Any word of a European release yet?
Not gonna lie, THIS is the reason I bought my 3DS
Hmm, not so sure about the art style. I mean, Layton and Wright are both cartoons (I know in MoM Layton's gone all 3D, but still), and this doesn't seem the nicest way to protray them personally. And surprisingly Wright looks better in 3D than Layton, perhaps because he's more realistic looking in the first place.
Still, it's the story that counts, and the gameplay, and the visuals still look great. And the cutscenes are drawn animations, so it's all good.
Don't like the Medieval theme.
Don't like the dialogue boxes.
Don't like the graphics.
Hate the new characters and the way they look, way too Phoenix Wright for Professor Layton.
I consider this a Phoenix Wright game rather than a Professor Layton game and in fact I hope that it is NOT part of the Professor Layton series and that Layton is just a guest. It looks that way anyway since there are no gameplay pictures with Layton or Luke yet.
When I saw the ad it looked amazing but now... not so great...
Looks fantastic,one of my most wanted 3DS games,can't wait to see some gameplay.
I would buy this game for one reason: to hear Professor Layton shout 'Objection!'

Looking to be an excellent culmination of the two games, and as a big fan of both I'm really looking forward to seeing how this one turns out.
ONM, don't hurt us any more! We won't be getting it and may swell face it.
