Cell phones forum: Planning for GALAXY NOTE..shud i wait ??

I had been pondering over which android Smartphone to buy, for some 5 months.

My priorities are
1.Large screen..( I mean it.. larger than 4.3")
2.High speed processor/gpu...
3.Feature rich....particularly high speed GPS lock and go, as I travel to new places a lot
4.Great looks ..indeed

After going through reviews of multiple websites (particularly cnet) I sorted out two Smartphone..
They are HTC sensation XL and Galaxy note..
Though the music quality in HTC with Beats headset, the UI and the trendy looks are exceptionally superb, I feel it's powerhouse is not really that powerful to handle graphic rich games and is not worth the money, which left me with only one choice.

That's SAMSUNG GALAXY NOTE.

Galaxy note has been around for some 5 months and I had been tracking its reviews and popularity from that time. Had hands-on demo several times. The slow-staggering UI sometimes makes me feel tat its not worth it, compared to the smooth UI of iphone that makes me feel so real. The decade old looks spoil the aesthetics as well. But still it satisfies every other priority of mine (Particularly the superfast GPS lock with GLONASS paired with A-GPS and smooth processing of intense graphics while playing games) with an added advantage of S-Pen which ain't that smooth and responsive, but works fine with little bit of getting-used-to-it stuff.

Everything has been set and I am all ready to buy this big thing in few days.

Now the rumors of Galaxy S3 is going around the web and the recently leaked specs is making me roam around in the state of dilemma.
I hope it will be the most powerful and attractive phone once its released.
Expected its release this MWC but ended in disappointment.
I am sure that its not gonna be released atleast this half of 2012 and am in a dire need of Smartphone within next 3 months.

Now my question is..

Can I go ahead and buy the galaxy note now?

Is galaxy note future proof and worth its money we put in it? Will it stay ahead of other phones in quality and features atleast till s3 is released?

Or should I wait for long long time and give a shot for S3?
