There may be a new launcher at some point, but it will almost certainly not come before the current 32-bit client is retired. A new launcher will very likely also only be 64-bit anyways.
The current 64-bit client though works perfectly fine (at least, for MOST people), so if it does not for you your focus should be in getting that one to work.
If you still have a computer that only has a 32-bit chip (which is likely from before 2010 somewhere), then it is really time to ask Santa for a new computer.... 64-bit computing has been a thing since before this game was even launched (Windows Vista came as 64-bit by default alongside a 32-bit version, and that was back in 2006) so if you still have a 32-bit OS running, it is really time to upgrade.
