If I'm already 4.1u so no problems if I buy the game?
If you buy an American copy upon release, no, nothing will happen CONSIDERING that the NTSC copy uses 4.1U. If you get a foreign copy (through methods of piracy or importing, I'm not one to judge), then regardless, it'll ask for an update to 4.1E (or 4.XJ if you decide to go that route and (don't know what the version will be, so I'm using X). But most homebrew bypasses updates anyway. I use Neogamma, no update problems. I think that Preloader offers a bypass, and there's brickblocker and all that floating around nowadays anyway.
tl;dr, there shouldn't be.
