Is it worth waiting for Nothing 4b??

My budget is 25k. Im gonna join for college, i need a phone for long term use(4 years atleast if possible),good camera(optional ig),now, my options are one plus nord ce 6 lite, one plus N6, which are on offer in amazon till 6th july. Im wondering whether to wait till 7th, for nothing 4b which is said to come at 25k, i was hoping to buy nothing 3a or cmf phone 2 pro but both are not deliverable or out of stock. Which should i choose? Should i wait for phone 4b?
