Speaking as a huge fan of Resident Evil 4;
I always loved this game, i must have played it hundreds of times. It's one of my all time favorite video games, and i can say without a doubt, my favorite RE game. With that out of the way...
Do i think that it needs a remake? No. I agree with fans who want to see Code Veronica remake instead. I think that CV deserves a remake because i think it has lot more potential to be even better game than the original.
But, as someone who loved remakes of RE 2 and 3, i can't help but to be interested in and curious about what would the remake of RE 4 be like. At the same time, just like other fans, i am also concerned about Capcom making way too many big changes and cuts (which they will most definitely make) on original game's content and story.
I'm sure everyone here still remember just how popular RE 4 was when it first came out, and the fact that even today it has such huge fan following and how it's considered a classic really shows how much this game is loved. If Capcom somehow figures out how to do a great job, i dare to say even better job with it than what they did so far with other remakes, there is a chance that same could happen to RE 4 remake. But that's just me being hopeful fan, because there's also a huge chance that it will never be as good as original.
I knew it was only matter of time when this news will be announced, specially after those rumors about RE 8 leaked out, which made that game sound like half-ass RE 4 remake. And if those other rumors about how RE 8 was based on now cancelled Revelations 3 are true, it really goes to show how Capcom already tried to work on something similar to RE 4 much earlier, and how maybe they already planned on remaking that game.
