Some Youtube channels are saying Bangladesh may go for 45 Tejas MK1A with local assembly.
I don't know their source of information.
What I know,
1. Bangladesh is looking at two stage procurement 1. MRCA and 2. Single Engine Light Fighters.
MRCA is a twin engine fighter. ( About 16 in number)
Single Engine fighter to replace the Chinese F7/ F7BGI ( 3 Squadron)
2. PM Sheikh Hasina has said that she wishes that Bangladesh produces ( read assembles) it's own fighter jet. [1]
3. A aeronautical unit ( possibly) for assembly was to be opened in Bangladesh [2].

So, my assessment is the following. It wouldn't be prudent for going for local assembly for 16 MRCA.
If local assembly is planned, it is for F7/F7BGI replacement.
BAF chief after his sortie in LCA Tejas also spoke that, they may consider Tejas as a contender for F7 replacement.
But, I don't think they are in any hurry, they want MRCA first. In any case, I don't expect any announcement before next year's air show in Dhaka as any announcement prior to the event will affect the participation in the air show.

As Bangladesh is traditionally a Chinese platform buyer in Defence sector, one would expect Chinese platform to be selected. But, these days, some fine underground rifts may be present between Dhaka and Beijing.
Also, JF17 is not participating in the next year air-show. So, it can be ruled out. That leaves only the J-10 as the Chinese platform. ( For F7 replacement).
On things favouring Tejas.
1. India has extended $500 million defence line of credit and can extend more if needed.
2. As Tejas mk1A isn't available today and would take 3 years to develop Indian version and further more 1-2 years for Bangladeshi version ( changing the Israeli parts). The intervening time can be used for building the assembly line in Bangladesh. And thus no loss or diversion in production capacity in India for IAF and other smaller orders.
3. Bangladesh too wants MRCA first, so wouldn't be bothered about the intervening time as long as local assembly is promised.
3. If Tejas line is created in Bangladesh, in future, MWF too may get assembled in Bangladesh.

I personally am not getting my hopes high for Tejas sale to Bangladesh. But can't reject the Idea either.
